 ITEM 1.    BUSINESS

GENERAL

Our mission is to enable people and businesses throughout the world to realize their full potential. We work to achieve our mission through technology that transforms the way people work, play, and communicate. Since our founding in 1975, we have been a leader in this transformation. We develop and market software, services, and solutions that we believe deliver new opportunity, convenience, and value to people’s lives. We do business throughout the world and have offices in more than 100 countries.

We generate revenue by developing, manufacturing, licensing, and supporting a wide range of software products for many computing devices. Our software products include operating systems for servers, personal computers, and intelligent devices; server applications for distributed computing environments; information worker productivity applications; business solution applications; high-performance computing applications, and software development tools. We provide consulting and product support services, and we train and certify computer system integrators and developers. We sell the Xbox 360 video game console and games, PC games, and peripherals. Online offerings and information are delivered through our Windows Live, Office Live, and MSN portals and channels.

We also research and develop advanced technologies for future software products. We believe that delivering breakthrough innovation and high-value solutions through our integrated software platform is the key to meeting our customers’ needs and to our future growth. We believe that over the past few years we have laid the foundation for long-term growth by delivering innovative new products, creating opportunities for partners, improving customer satisfaction, putting many of our most significant legal challenges behind us, and improving our internal processes. Our focus is to build on this foundation by continuing to innovate on our integrated software platform, delivering compelling value propositions to customers, responding effectively to customer and partner needs, and continuing to focus internally on product excellence, business efficacy, and accountability. Our research and development facilities are located primarily in Redmond, Washington. We also have smaller research facilities in other parts of the United States and around the world, including, but not limited to, China, Denmark, England, India, Ireland, and Israel.

OPERATING SEGMENTS

Our segments provide management with a comprehensive financial view of our key businesses. The segments provide a framework for the alignment of strategies and objectives across the development, sales, marketing, and services organizations, and for the timely and rational allocation of development, sales, marketing, and services resources within businesses. The segments also help focus strategic planning efforts on key objectives and initiatives across our businesses.

Table of Contents

 Part I 

Item 1

Due to our integrated business structure, operating costs included in one segment may benefit other segments. Therefore, these segments are not designed to measure operating income or loss that is directly related to the products included in each segment. Inter-segment cost commissions are estimated by management and used to compensate or charge each segment for such shared costs and to motivate shared effort. Segments should not be viewed as discrete or easily separable businesses.

For the fiscal years covered by this filing, our seven segments were: Client; Server and Tools; Information Worker; Microsoft Business Solutions; MSN; Mobile and Embedded Devices; and Home and Entertainment. See Note 18 – Segment Information of the Notes to Financial Statements for financial information regarding segment reporting. On July 17, 2006, we announced a change in our operating segments reflecting the culmination of the business realignment announced in September 2005. These changes will be effective for fiscal year 2007; the seven segments discussed in this section are presented in the way we internally managed and monitored performance at the business group level in fiscal year 2006, 2005, and 2004.

Client

Client has overall responsibility for the technical architecture, engineering and product delivery of our Windows product family, and is also responsible for our relationships with personal computer manufacturers, including multinational and regional original equipment manufacturers (“OEMs”). The segment includes sales and marketing expenses for the Windows client operating system and product development efforts for the Windows platform. Client revenue growth is correlated with the growth of purchases of personal computers from OEMs that pre-install versions of Windows operating systems because the OEM channel accounts for over 80% of total Client revenue.

The next generation of the Windows operating system, Windows Vista, is under development. This development phase represents a major investment that we expect will result in a significantly more manageable and powerful PC operating system than previously released by Microsoft. Windows Vista will include advances in security, digital media, user interfaces, and other areas that will enhance the user and developer experience.

Products:    Windows XP Professional and Home; Media Center Edition; Tablet PC Edition; and other standard Windows operating systems.

Competition

Client faces strong competition from well-established companies with differing approaches to the PC market. Competing commercial software products, including variants of Unix, are supplied by competitors such as Apple Computer, Hewlett-Packard, IBM, and Sun Microsystems. The Linux operating system, which is also derived from Unix and is available without payment under a General Public License, has gained some acceptance as competitive pressures lead PC OEMs to reduce costs. The Windows operating system also faces competition from alternative platforms and new devices that may reduce consumer demand for traditional personal computers. Competitors such as Mozilla offer software that competes with the Internet Explorer Web browsing capabilities of Windows products. Apple Computer, Real Networks, and others compete with Windows Media Player. Our operating system products compete effectively by delivering innovative software, a familiar, easy-to-use interface, compatibility with a broad range of hardware and software applications, and the largest support network for any operating system.

Server and Tools

Server and Tools develops and markets Windows Server products, including Windows Server operating systems. Windows Server products are integrated server infrastructure software that are designed to support end-to-end software applications and tools built on the Windows Server 2003 operating system. Windows Server products include the server platform, operations, security, applications and collaboration software. The segment also builds standalone and software development lifecycle tools for software architects, developers, testers and project managers.

We offer a broad range of consulting services and provide product support services. The segment also provides training and certification to developers and information technology professionals about our Server and PC platform products. Server and Tools also includes the Enterprise Partner Group, which is responsible for sales, partner management and partner programs for medium and large organizations; and the Public Sector sales and marketing organization.

Table of Contents

 Part I 

Item 1

Approximately half of Server revenue comes from multi-year licensing agreements, one third is purchased through fully packaged product and transactional volume licensing programs, and approximately 10% comes from licenses sold to OEMs. Approximately 15% of revenue comes from consulting and product support services.

Products and Services:    Windows Server operating system; Microsoft SQL Server; Exchange Server; Microsoft Consulting Services; product support services; Visual Studio; System Center products; Forefront security family of products; and Biz Talk Server, among others.

Competition

Our server operating system products face intense competition from a wide variety of server operating systems and server applications, offered by companies with a variety of market approaches. Vertically integrated computer manufacturers such as Hewlett-Packard, IBM, and Sun Microsystems offer their own variant of Unix preinstalled on server hardware. Nearly all computer manufacturers offer server hardware for the Linux operating system. IBM’s endorsement of Linux has aided the acceptance of Linux as an alternative to Unix and Windows server operating systems. Linux’s competitive position has also benefited from the large number of compatible applications now produced by many leading commercial software developers and non-commercial software developers. A number of companies supply versions of Linux, including Novell and Red Hat.

We compete in the business of providing enterprise-wide computing solutions with several companies that provide solutions and middleware technology platforms. IBM and Sun Microsystems lead a group of companies focused on the Java 2 Platform Enterprise Edition (J2EE). Commercial software developers that provide competing server applications for PC-based distributed client/server environments include CA, IBM, and Oracle.

Numerous commercial software vendors offer competing commercial software applications for connectivity (both Internet and intranet), security, hosting, and e-business servers. System Center competes with BMC, CA, and IBM in the Management of IT infrastructures, while Forefront Security competes with McAfee, Symantec, and Trend Micro in protecting both client and server applications. In addition, IBM has a large installed base of Lotus Notes and cc:Mail, both of which compete with our collaboration and e-mail products. Non-commercial software products, including the widely-deployed Apache Web Server, also compete with our solutions. Our products for software developers compete against offerings from Adobe, BEA Systems, Borland, IBM, Oracle, Sun Microsystems, and other companies. We believe that our server products provide customers with advantages in innovation, performance, total costs of ownership, and productivity, by delivering superior applications development tools and development environment, compatibility with a broad base of hardware and software applications, security, and manageability.

Information Worker

Information Worker consists of the Microsoft Office system of programs, services, and software solutions designed to increase personal, team, and organization productivity. The Office system offerings generate over 85% of Information Worker revenue. Revenue growth depends on our ability to add value to the core Office product set and to continue to expand our product offerings in other information worker areas such as enterprise content management, collaboration, unified messaging, and business intelligence.

Approximately 40% of Information Worker revenue has come from multi-year license agreements with large enterprises. Revenues from these licenses generally depend upon the number of information workers in a licensed enterprise. Revenue from this category of agreements is therefore relatively independent of the number of PCs sold in a given year. Consequently, general employment levels, particularly in North America and Europe, significantly affect Information Worker revenue. Approximately 40% of Information Worker revenue comes from new licenses acquired through fully packaged product and volume licensing programs to individual consumers and enterprises of all sizes. Most of this revenue is sensitive to information technology budgets, which often depend on general economic conditions. The remaining approximately 20% of Information Worker revenue comes from licenses to OEMs for new PCs and is affected by the level of PC shipments. The next wave of our flagship product, the 2007 Microsoft Office system, is currently under development.

Products:    Microsoft Office; Microsoft Project; Microsoft Visio; SharePoint Portal Server CAL; Microsoft Live Meeting; One Note; and Office Communication Server.

 Part I 

Item 1

Competition

Competitors to the Microsoft Office system include many software application vendors such as Apple, Corel, Google, IBM, Novell, Oracle, Red Hat, Sun Microsystems, and local application developers in Europe and Asia. IBM (Smartsuite) and Corel (WordPerfect Suite) have measurable installed bases with their office productivity products. Apple may distribute certain of their application software products with various models of their PCs. The OpenOffice.org project provides a freely downloadable cross-platform application that also has been adapted by various commercial software vendors to sell under their brands, including IBM, Novell, Red Hat, and Sun. Corel’s suite and many local software suites around the world are aggressively priced for OEMs to preinstall on low-priced PCs. In addition to traditional client-side applications, Web-based offerings such as AjaxWrite, gOffice, iNetOffice, SimDesk, ThinkFree, wikiCalc, or other small projects competing with individual applications, can also provide an alternative to Microsoft Office system products. Google has announced spreadsheet and word processing applications as web-based offerings and also provides an enterprise search offering that competes with SharePoint and our new enterprise search product. IBM has many different points of competition with Office system products with its Notes and Workplace offerings.

As we continue to respond to market demand for additional functionality and products, we will compete with additional vendors, most notably in enterprise content management, collaboration tools, unified messaging, and business intelligence. These competitors include WebEx, and a number of business intelligence vendors such as Business Objects, Cognos, and Hyperion.

Microsoft Business Solutions

Microsoft Business Solutions is responsible for Microsoft Dynamics brand business applications for small and mid-size businesses, large organizations and divisions of global enterprises. It offers financial management, customer relationship management, supply chain management, and analytics applications. Revenue is derived from software and services sales, with software sales representing a large majority of total revenue. Software revenues include both new software licenses and enhancement plans, which provide customers with future software upgrades and on-line training over the period of the plan. The solutions are delivered through a worldwide network of channel partners and independent software vendors that provide services, additional related software, and local support.

Products:    Microsoft Dynamics AX; Microsoft Dynamics CRM; Microsoft Dynamics GP; Microsoft Dynamics NAV; Microsoft Dynamics SL; Microsoft Dynamics Retail Management System; Microsoft Partner Program; and Microsoft Office Small Business Accounting.

Competition

Our competition varies based upon the size and geographic location of the customer for whom we are competing. We compete with well-known vendors such as Intuit and Sage in the market focused on providing solutions for small and mid-sized businesses. The market for large organizations and divisions of global enterprises continues to be intensely competitive with a small number of primary vendors including Oracle and SAP. Additionally, these large enterprise-focused vendors are repositioning some of their business applications to focus on small and mid-sized businesses. We believe our products compete effectively with these vendors based on our strategy of providing integrated, adaptable solutions that work like and with Microsoft technologies our customers already have.

MSN

MSN provides personal communications services, such as e-mail and instant messaging, and online information offerings such as MSN Search, MapPoint, and the MSN portals and channels around the world. MSN also provides a variety of online paid offerings. MSN manages many of its own properties, including health, autos, and shopping. MSN also creates alliances with third parties for many channels, including CareerBuilder.com, Expedia.com, Foxsports.com, Match.com, and MSNBC.com.

MSN generates revenue primarily from advertisers on MSN, from consumers and partners through subscriptions and transactions, and from MSN narrowband Internet access subscribers. In fiscal year 2006, we launched MSN adCenter – our internally developed advertising platform – in certain international markets and throughout the U.S. where it now serves 100 percent of paid search traffic on our online properties. We believe MSN adCenter will enable us to increase both display and search advertising revenues by reducing our reliance on third parties for delivering

ads. In fiscal year 2006, we announced Windows Live™, a set of Internet services and software designed to improve the users’ connected experience and we released Windows Live Messenger to consumers in 58 countries.

Products:    MSN Search; MapPoint; MSN Internet Access; MSN Premium Web Services (consisting of MSN Internet Software Subscription, MSN Hotmail Plus, MSN Bill Pay, and MSN Radio Plus); Windows Live; and MSN Mobile Services.

Competition

MSN competes with AOL, Google, Yahoo!, and a wide array of Web sites and portals that provide content and online offerings of all types to end users. We compete with these organizations to provide advertising opportunities for merchants. MSN also competes for narrowband Internet access users with AOL, Earthlink, and other ISPs for dial-up internet access in the United States. Due to the continuing trend of consumers migrating from narrowband to broadband Internet access, we expect our narrowband Internet access subscriber base to continue to decline as we de-emphasize this portion of our business. The Internet advertising industry has grown significantly over the past several years, and we anticipate that this trend will continue. Competitors are aggressively developing Internet offerings that seek to provide more effective ways of connecting advertisers with audiences through enhanced functionality in communication services, improvements in information services such as Internet search, and improved advertising infrastructure and support services. We have developed our own algorithmic search engine to provide end users with more relevant search results, a broader selection of content, and expanded search services. To support the growth of our advertising business, we also are investing in our communication services, technology, operations, and sales efforts. We will continue to introduce new products and services, including the Windows Live set of services that are aimed at attracting additional users through improvements in the user online experience. We believe that we can compete effectively across the breadth of our Internet services by providing users with software innovation in the form of information and communication services that help them find, discover, and experience what they want online and by providing merchants with effective advertising results through improved systems and sales support.

Mobile and Embedded Devices

Mobile and Embedded Devices develops and markets products that extend the Windows platform to mobile devices such as PDAs and phones, and to embedded devices. Microsoft’s vision for mobile devices is rooted in the convergence of the computing and wireless industries, which we believe creates new opportunities to improve communication and information access for customers. We see software as a key differentiator in making smart devices and wireless data services valuable to customers through rich experiences such as mobile messaging, location-based services, media, and speech recognition. We are working closely with mobile operators and with hardware and software partners to accelerate the development and availability of smart devices and services, and to provide a broad range of choices for customers. The segment is also responsible for managing our company-wide sales and customer relations with device manufacturers and other communication-sector customers, which includes network service providers and media and entertainment companies. Windows Embedded is a suite of operating systems, tools, and technologies that are specifically designed for today’s advanced embedded devices.

Products:    Windows Mobile software platform; Windows Embedded device operating system; and Windows Automotive.

Competition

Windows Mobile software faces substantial competition from Nokia, Openwave Systems, Palm, QUALCOMM, Research In Motion, and Symbian. The embedded operating system segment is highly fragmented with many competitive offerings. Key competitors include IBM, Wind River, and versions of embeddable Linux from commercial Linux vendors such as Metrowerks and MontaVista Software. The telematics market is also highly fragmented, with competitive offerings from IBM and automotive suppliers building on various real-time operating system platforms from commercial Linux vendors, QNX Software Systems, Wind River, and others. We believe that our products compete effectively by providing a familiar development framework, which enables developers to easily write and deploy innovative applications for mobile or embedded devices. We also compete by providing a flexible platform that allows customers and partners to build differentiated and profitable business models, and by providing end users with benefits such as ease of use, personal productivity, and better information management and control.

Item 1

Home and Entertainment

Home and Entertainment is responsible for development, production, and marketing for the Xbox video game system, including consoles and accessories, third-party games, games published under the Microsoft brand, and Xbox Live operations, research, and sales and support. In addition to Xbox, we offer several types of entertainment products, including PC software games, online games, and other devices. The segment also leads the development efforts of our Consumer Productivity Experience Group (“CPxG”) which includes Microsoft’s line of consumer software and hardware products, such as the Encarta line of learning products and services, application software for Macintosh computers, and Microsoft PC hardware products such as mice and keyboards. In addition, the segment carries out all retail sales and marketing for Microsoft Office and the Windows operating systems (for which it receives an inter-segment commission), Xbox, PC games, and CPxG products. It also is responsible for the development, sales, and deployment of Microsoft’s TV platform products for the interactive television industry, including MSTV Foundation Edition and Internet Protocol TV products.

Products:    Xbox 360; Xbox; Xbox Live; CPxG (consumer software and hardware products); and IPTV.

Competition

The home and entertainment business is highly competitive, characterized by rapid product life cycles, frequent introductions of new products and titles, and the development of new technologies. The markets for our products are characterized by significant price competition. We anticipate continued pricing pressure from our competitors. From time to time, we have responded to this pressure by reducing prices on certain products. Our competitors vary in size from very small companies with limited resources to very large, diversified corporations with substantial financial and marketing resources. We compete primarily on the basis of product innovation, quality and variety, timing of product releases, and effectiveness of distribution and marketing.

Our Xbox hardware business competes with console platforms from Nintendo and Sony, both of which have a large, established base of customers. The lifecycle for video game consoles averages 5 to 7 years. We released Xbox 360, our next generation console in November 2005. Nintendo and Sony have also announced new versions of their game consoles, which have not been released. Success in the transition to the next generation of consoles will depend on the availability of games for the console, providing exclusive game content that gamers seek, the computational power of the console, and the ability to create new revenue sources such as advertising and downloadable content. We believe the Xbox 360 is positioned well against competitive console products based on significant innovation in hardware architecture, new developer tools, expanded revenue sources, and continued strong exclusive content from our own game franchises such as Halo.

In addition to competing against software published for non-Xbox platforms, our games business also competes with numerous companies that we have licensed to develop and publish software for the Xbox consoles. Our PC hardware products face aggressive competition from computer and other hardware manufacturers, many of which are also current or potential partners. Our MSTV business faces competition primarily from ad hoc solutions that address sub-segments of the TV delivery platform, but that do not provide end-to-end solutions for the network operator.

OPERATIONS

To serve the needs of customers around the world and to improve the quality and usability of products in international markets, we “localize” many of our products to reflect local languages and conventions. Localizing a product may require modifying the user interface, altering dialog boxes, and translating text.

Our operational centers support all operations in their regions, including customer contract and order processing, credit and collections, information processing and vendor management and logistics. The regional center in Ireland supports the EMEA region; the center in Singapore supports the Japan, Greater China and Asia-Pacific region; and the centers in Fargo, Puerto Rico, Reno, and Redmond support North America and Latin America.

We contract most of our manufacturing activities to third parties who produce the Xbox, various retail software packaged products, and Microsoft hardware. Our products may include some components that are available from only one or limited sources. Our Xbox 360 console includes certain key components that are supplied by a single source. The central processing unit is purchased from IBM and the graphics chips and embedded dynamic random access memory chips for the graphics processing unit are purchased from Taiwan Semiconductor Manufacturing Company and NEC Corporation, respectively. Although we have chosen to initially source these key Xbox 360 components from

Table of Contents

Item 1

a single supplier, we are under no obligation to exclusively source components from these vendors in the future. Beyond the exceptions noted, we generally have the ability to use other custom manufacturers if the current vendor becomes unavailable. We generally have multiple sources for raw materials, supplies, and components, and are often able to acquire component parts and materials on a volume discount basis.

PRODUCT DEVELOPMENT

During fiscal years 2006, 2005, and 2004, research and development expense was $6.58 billion, $6.10 billion, and $7.74 billion, respectively. Those amounts represented 14.9%, 15.3%, and 21.0%, respectively, of revenue in each of those years. We plan to continue significant investment in a broad range of research and product development.

Most of our software products are developed internally. We also purchase technology, license intellectual property rights, and oversee third-party development and localization of certain products. We believe we are not materially dependent upon licenses and other agreements with third parties relating to the development of our products. Internal development allows us to maintain closer technical control over our products. It also gives us the freedom to decide which modifications and enhancements are most important and when they should be implemented. Generally, we also create product documentation internally. We strive to obtain information at the earliest possible time about changing usage patterns and hardware advances that may affect software design. Before releasing new software platforms, we provide application vendors with a range of resources and guidelines for development, training, and testing.

Business and Product Development Strategy.    Innovation is a key factor affecting Microsoft’s growth. In fiscal year 2006, we received our 5,000^th patent. We continue our long-term commitment to research and development, including advanced work aimed at innovations in a wide spectrum of technologies: tools and platforms; communication, collaboration and expression; information access and organization; entertainment; business and e-commerce; and devices. Through innovations in these areas, we expect to grow revenue via three principal strategies:

Leading the Software Services Transformation

Internet-based services are transforming the way people create, deploy, manage and use technology. We are committed to playing a leadership role in the software services transformation through our efforts to create our services platform for the next generation of applications, communications, and commerce. Across the company, software services are at the core of our development efforts.

Table of Contents

 Part I 

Item 1

In fiscal year 2006, we introduced Windows Live and Office Live, which provides small businesses with affordable Internet-based business services hosted by Microsoft. We rolled out new search services, including beta releases of Windows Live Search and Windows Live Academic Search. We introduced new and enhanced services for computer safety and computer maintenance (Windows Live SafetyCenter and Windows Live OneCare), communications (Windows Live Mail and Windows Live Messenger), and entertainment (Xbox Live). We also created Live Labs, an applied research program that targets Internet products and services.

Because software services offer strong opportunities for growth, we will continue to refine and improve adCenter, our advertising engine for Windows Live, MSN and other online offerings. We will deploy new service-based solutions, including Dynamics CRM Live, which we announced in July 2006. We will also continue to build out our services infrastructure, providing new tools to help partners and businesses create and host services, and adding new data centers to meet growing consumer demand for services.

DISTRIBUTION, SALES AND MARKETING

We distribute our products primarily through the following channels: OEM; distributors and resellers; and online.

OEM.    Our operating systems are licensed primarily to OEMs under agreements that grant the OEMs the right to build computing devices based on our operating systems, principally PCs. Under similar arrangements, we also market and license certain server operating systems, desktop applications, hardware devices, and consumer software products to OEMs. We have OEM agreements covering one or more of our products with virtually all of the major PC OEMs, including Acer, Dell, Fujitsu, Fujitsu Siemens Computers, Gateway, Hewlett-Packard, Lenovo, NEC, Samsung, Sony, and Toshiba. A substantial amount of OEM business is also conducted with system builders, which are low-volume customized PC vendors operating in local markets.

Distributors and Resellers.    We license software to organizations under arrangements that allow the end-user customer to acquire multiple licenses of products. Organizations license our products primarily through large account resellers (“LARs”), direct market resellers, and value-added resellers (“VARs”). Many organizations that license products through enterprise agreements (“EAs”) transact directly with us, with sales support from our Enterprise Software Advisor channel partners. These Enterprise Software Advisors typically are also authorized as LARs and operate as resellers for our other licensing programs. Although each type of reselling partner reaches organizations of all sizes, LARs are primarily engaged with large organizations and VARs typically reach the breadth of small- and medium-sized organizations. Some of our distributors include Ingram Micro and Tech Data, and some of our largest resellers include CDW, Dell, Insight Enterprises, Software House International, and Software Spectrum. Our business solutions software offerings are licensed to enterprises through a global network of channel partners providing vertical solutions and specialized services. We distribute our finished goods products primarily through independent non-exclusive distributors, authorized replicators, resellers, and retail outlets. Individual consumers obtain our products primarily through retail outlets, including Best Buy, Target, and Wal-Mart. We have a network of field sales representatives and field support personnel that solicits orders from distributors and resellers and provides product training and sales support.

Our arrangements for organizations to acquire multiple licenses of products are designed to provide them with a means of doing so without having to acquire separate packaged product through retail channels. In delivering organizational licensing arrangements to the market, we use different programs designed to provide flexibility for organizations of various sizes. While these programs may differ in various parts of the world, generally they include:

Open.    Designed primarily for small-to-medium organizations (5 to over 250 licenses), this program allows customers to acquire perpetual licenses and, at the customer’s election, rights to future versions of software products over a specified time period (generally two years). The offering that conveys rights to future versions of certain software product over the contract period is called Software Assurance. Software Assurance also provides support, tools, and training to help customers deploy and use software efficiently. Under the Open program, customers can acquire licenses only, or licenses with Software Assurance. They can also renew Software Assurance upon the expiration of existing volume licensing agreements.

Select.    Designed primarily for medium-to-large organizations (greater than 250 licenses), this program allows customers to acquire perpetual licenses and, at the customer’s election, Software Assurance, which consists of rights to future versions of certain software products, support, tools, and training over a specified time period (generally three years). Similar to the Open program, customers can acquire licenses only, acquire licenses with Software Assurance, or renew Software Assurance upon the expiration of existing volume licensing agreements.

Enterprise Agreement.    The Enterprise Agreement is targeted at medium and large organizations that want to acquire perpetual licenses to software products for all or substantial parts of their enterprise, along with rights to future versions of certain software products, support, tools, and training over a specified time period (generally three years).

Online Services.    We distribute online content and services through MSN and other online channels. MSN delivers Internet access and various premium services and tools to consumers. MSN also delivers online e-mail and messaging communication services and information services such as online search, advertising, and premium content. Home and Entertainment operates the Xbox Live service which allows customers to participate in the gaming experience with other subscribers online. Microsoft Business Solutions operates the Microsoft Small Business Center portal, which is delivered online. This portal provides tools and expertise for small-business owners to build, market, and manage their businesses online. Other services delivered online include Microsoft Developer Networks subscription content and updates, periodic product updates, and online technical and practice readiness resources to support our partners in developing and selling our products and solutions.

CUSTOMERS

Our customers include individual consumers, small and medium-sized organizations, enterprises, governmental institutions, educational institutions, Internet Service Providers, application developers, and OEMs. Consumers and small- and medium-sized organizations obtain our products primarily through resellers and OEMs. Sales to Dell and its subsidiaries in the aggregate accounted for approximately 11% of fiscal year 2006 and 10% in each of fiscal year 2005 and 2004 revenue. These sales were made primarily through our OEM and volume licensing channels and cover a broad array of products including Windows PC operating systems, Microsoft Office, and server products. Our practice is to ship our products promptly upon receipt of purchase orders from customers; consequently, backlog is not significant.

 ITEM 1A.    RISK FACTORS

Challenges to our business model may reduce our revenues and operating margins.    Our business model has been based upon customers paying a fee to license software that we developed and distributed. Under this license-based software model, software developers bear the costs of converting original ideas into software products through investments in research and development, offsetting these costs with the revenue received from the distribution of their products. We believe the license-based software model has had substantial benefits for users of software, allowing them to rely on our expertise and the expertise of other software developers that have powerful incentives to develop innovative software that is useful, reliable, and compatible with other software and hardware. In recent years

Table of Contents

 Part I 

Item 1A

certain “open source” software business models have evolved into a growing challenge to our license-based software model. Open source commonly refers to software whose source code is subject to a license allowing it to be modified, combined with other software and redistributed, subject to restrictions set forth in the license. A number of commercial firms compete with us using an open source business model by modifying and then distributing open source software to end users at nominal cost and earning revenue on complementary services and products. These firms do not have to bear the full costs of research and development for the software. A prominent example of open source software is the Linux operating system. While we believe our products provide customers with significant advantages in security and productivity, and generally have a lower total cost of ownership than open source software, the popularization of the open source software model continues to pose a significant challenge to our business model, including continuing efforts by proponents of open source software to convince governments worldwide to mandate the use of open source software in their purchase and deployment of software products. To the extent open source software gains increasing market acceptance, sales of our products may decline, we may have to reduce the prices we charge for our products, and revenue and operating margins may consequently decline.

Another development is the software-as-a-service business model, by which companies provide applications, data, and related services over the Internet. Providers use primarily advertising or subscription-based revenue models. Recent advances in computing and communications technologies have made this model viable and enabled the rapid growth of some of our competitors. We are devoting significant resources toward developing our own software-as-a-service strategies. It is uncertain whether these strategies will prove successful.

We face intense competition.    We continue to experience intense competition across all markets for our products and services. Our competitors range in size from Fortune 100 companies to small, specialized single-product businesses and open source community-based projects. While we believe the breadth of our businesses and product portfolio offers benefits to our customers that are a competitive advantage, our competitors that are focused on a narrower product line may be more effective in devoting technical, marketing, and financial resources to compete with us. In addition, barriers to entry in our businesses generally are low. The Internet as a distribution channel and the non-commercial software model described above have reduced barriers to entry even further. Open source software vendors are devoting considerable efforts to developing software that mimics the features and functionality of our products. In response to competitive factors, we are developing versions of our products with basic functionality that are sold at lower prices than the standard versions. These competitive pressures may result in decreased sales volumes, price reductions, and/or increased operating costs, such as for marketing and sales incentives, resulting in lower revenue, gross margins and operating income.

We may not be able to protect our intellectual property rights against piracy, infringement of our patents by third parties, or declining legal protection for intellectual property.    We defend our intellectual property rights and combat unlicensed copying and use of software and intellectual property rights through a variety of techniques. Preventing unauthorized use or infringement of our rights is difficult. Piracy of our products represents a loss of revenue to us. While this adversely affects U.S. revenue, the impact on revenue from outside the United States is more significant, particularly in countries where laws are less protective of intellectual property rights. Similarly, the absence of harmonized patent laws makes it more difficult to ensure consistent respect for patent rights. Future legal changes could make this even more challenging. Throughout the world, we actively educate consumers about the benefits of licensing genuine products and obtaining indemnification benefits for intellectual property risks, and we educate lawmakers about the advantages of a business climate where intellectual property rights are protected. However, continued educational and enforcement efforts may fail to enhance revenue. Reductions in the legal protection for software intellectual property rights or compliance with additional intellectual property obligations impacting the rights of software developers could both adversely affect revenue.

Third parties may claim we infringe their intellectual property rights.    From time to time we receive notices from others claiming we infringe their intellectual property rights. The number of these claims may grow. Responding to these claims may require us to enter into royalty and licensing agreements on less favorable terms, require us to stop selling or to redesign affected products, or to pay damages or to satisfy indemnification commitments with our customers including contractual provisions under various license arrangements. If we are required to enter into such agreements or take such actions, our operating margins may decline as a result. We have made and expect to continue making significant expenditures to settle claims related to the use of technology and intellectual property rights as part of our strategy to manage this risk.

Item 1A

We may not be able to protect our source code from copying if there is an unauthorized disclosure of source code.    Source code, the detailed program commands for our operating systems and other software programs, is critical to our business. While we license certain portions of our source code for various software programs and operating systems to a number of licensees, we take significant measures to protect the secrecy of large portions of our source code. If an unauthorized disclosure of a significant portion of our source code occurs, we could potentially lose future trade secret protection for that source code. The loss of future trade secret protection could make it easier for third parties to compete with our products by copying functionality, which could adversely affect our revenue and operating margins. Unauthorized disclosure of source code could also increase certain risks described in the next paragraph.

Security vulnerabilities in our products could lead to reduced revenues or to liability claims.    Maintaining the security of computers and computer networks is a critical issue for us and our customers. Hackers develop and deploy viruses, worms, and other malicious software programs that attack our products. While this is an industry-wide problem that affects computers across all platforms, it affects our products in particular because hackers tend to focus their efforts on the most popular operating systems and programs and we expect them to continue to do so. We devote significant resources to address these critical issues. We focus on engineering even more secure products, enhancing security and reliability options and settings when we deliver products, and providing guidance to help our customers make the best use of our products and services to protect against computer viruses and other attacks on their computing environment. In addition, we are working to improve the deployment of software updates to address security vulnerabilities discovered after our products are released. We are also investing in mitigation technologies that help to secure customers from attacks even when such software updates are not deployed. We advise customers on how to help protect themselves from security threats through the use of our online automated security tools, our published security guidance, and the deployment of security software such as firewalls, anti-virus, and other security software. The cost of these steps could reduce our operating margins. Despite these efforts, actual or perceived security vulnerabilities in our products could lead some customers to seek to return products, to reduce or delay future purchases, or to use competing products. Customers may also increase their expenditures on protecting their existing computer systems from attack, which could delay adoption of new technologies. Any of these actions by customers could adversely affect our revenue. In addition, actual or perceived vulnerabilities may lead to claims against us. While our license agreements typically contain provisions that eliminate or limit our exposure to such liability, there is no assurance these provisions will be held effective under applicable laws and judicial decisions.

We are subject to government litigation and regulatory activity that affects how we design and market our products.    As a leading global software maker we receive scrutiny from government agencies under U.S. and foreign competition laws. Some jurisdictions also provide private rights of action for competitors or consumers based on alleged anti-competitive conduct. For example, we have been involved in the following actions.

Lawsuits brought by the U.S. Department of Justice, 18 states, and the District of Columbia in two separate actions were resolved through a Consent Decree that took effect in November 2001 and a Final Judgment entered in November 2002. These proceedings imposed regulatory constraints on our Windows operating system businesses, including limits on certain contracting practices, required disclosure of certain software program interfaces, limits on Microsoft’s ability to ensure the visibility of certain Windows features in new PCs, and required licensing of certain communications protocols. While we believe we currently are in full compliance with the Decree and Judgment, if we fail to comply with them in the future additional restrictions could be imposed on us that would adversely affect our business.

In March 2004, the European Commission determined that we must create new versions of Windows that do not include certain multimedia technologies, many of which are required for certain Web sites, software applications and other aspects of Windows to function properly, and we must provide our competitors with specifications for how to implement certain communications protocols supported in Windows. Microsoft has appealed both determinations to European courts. As a result of the Commission decision, we have incurred and will (absent a reversal of this ruling) continue to incur duplicative development costs. The Commission ruling obligates Microsoft to make available specifications for certain Windows communications protocol technologies on licensing terms that are closely regulated by the Commission. The availability of these licenses may enable competitors to develop software products that better mimic the functionality of Microsoft’s own products which could result in a reduction in sales of our products. Pending resolution of Microsoft’s appeal, there will remain uncertainty about the legal principles that govern

Item 1A

product design issues for future releases of Microsoft products in Europe. These uncertainties could cause Microsoft to modify product design and delay release dates for Windows or other products.

In December 2005, the Korean Fair Trade Commission (“KFTC”) completed an investigation of whether including streaming media technology or instant messenger technology in Windows, or including Windows Media Services as an optional component of Windows Server, violates the Korean Fair Trade Law. The KFTC ruled that we had violated the law and issued a remedial order requiring us to offer two versions of Windows PC operating systems, one with Windows Media Player and Instant Messenger removed and another with those functionalities but also including opportunities for OEMs to install competing media player and instant messenger programs. If upheld on appeal, these remedies could adversely affect the utility and competitive position of Windows PC operating systems in the Korean market.

We believe our integrated approach to delivery of product innovation benefits consumers and business. Current or future government regulatory efforts and court decisions may hinder or delay our ability to provide these benefits thereby reducing the attractiveness of our products and the revenues that come from them. Moreover, there always remains the risk of new legal action, either by these or other governments or private claimants including with respect to products or features that haven’t been scrutinized or been the subject of objections in the past. The outcome of such legal actions could adversely affect us in a variety of ways, including:

Our online offerings are subject to government regulation of the Internet domestically and internationally in areas such as user privacy, data protection, and online content. The application of these laws and regulations to our business is often unclear and sometimes may conflict. Compliance with these regulations may involve significant costs or require changes in business practices that result in reduced revenue. Noncompliance could result in penalties being imposed on us or orders that we cease conducting the noncompliant activity.

Our business depends largely on our ability to attract and retain talented employees.    Our business is based on successfully attracting and retaining talented employees. The market for highly skilled workers in our industry is extremely competitive. We are limited in our ability to recruit internationally by restrictive domestic immigration laws. If we are less successful in our recruiting efforts, or if we are unable to retain key employees, our ability to develop and deliver successful products and services may be adversely affected.

Delays in product development schedules may adversely affect our revenues.    The development of software products is a complex and time-consuming process. New products and enhancements to existing products can require long development and testing periods. Significant delays in new product releases or significant problems in creating new products could adversely affect our revenue.

We make significant investments in new products and services that may not be profitable.    We have made and will continue to make significant investments in research, development, and marketing for new products, services, and technologies, including Windows Vista, the 2007 Microsoft Office system, Xbox 360, MSN Search, Windows Server and Windows Live. Investments in new technology are inherently speculative. Commercial success depends on many factors including innovativeness, developer support, and effective distribution and marketing. Significant revenue from new product and service investments may not be achieved for a number of years, if at all. Moreover, new products and services may not be profitable, and even if they are profitable, operating margins for new products and businesses may not be as high as the margins we have experienced historically.

 Part I 

Item 1A

Declines in demand for software could occur.    If overall market demand for PCs, servers, and other computing devices declines significantly, or consumer or corporate spending for such products declines, our revenue will be adversely affected. In addition, our revenue would be unfavorably impacted if customers reduce their purchases of new software products or upgrades to existing products because new product offerings are not perceived as providing significant new functionality or other value to prospective purchasers. We are making significant investments in Windows Vista and the 2007 Microsoft Office system. If these products are not perceived as offering significant new functionality or value to prospective purchasers, our revenue and operating margins could be adversely affected.

We have claims and lawsuits against us that may result in adverse outcomes.    We are subject to a variety of claims and lawsuits. Adverse outcomes in some or all of the claims pending against us may result in significant monetary damages or injunctive relief against us that could adversely affect our ability to conduct our business. While management currently believes that resolving all of these matters, individually or in the aggregate, will not have a material adverse impact on our financial position or results of operations, the litigation and other claims are subject to inherent uncertainties and management’s view of these matters may change in the future. There exists the possibility of a material adverse impact on our financial position and the results of operations for the period in which the effect of an unfavorable final outcome becomes probable and reasonably estimable.

We may have additional tax liabilities.    We are subject to income taxes in both the United States and numerous foreign jurisdictions. Significant judgment is required in determining our worldwide provision for income taxes. In the ordinary course of our business, there are many transactions and calculations where the ultimate tax determination is uncertain. We are regularly under audit by tax authorities. Although we believe our tax estimates are reasonable, the final determination of tax audits and any related litigation could be materially different from our historical income tax provisions and accruals. Based on the results of an audit or litigation, a material effect on our income tax provision, net income or cash flows in the period or periods for which that determination is made could result.

We may be at risk of having insufficient supplies of certain Xbox 360 components or console inventory.    Some components of the Xbox 360 are obtained from a single supplier and others may be subject to an industry-wide supply shortage. If a component delivery from a sole-source supplier is delayed or becomes unavailable or industry shortages occur, we may be unable to obtain replacement supplies on a timely basis, resulting in reduced console and game sales. Components are ordered based on forecasted console demand so we may experience component shortages for the Xbox 360 or, alternatively, excess console inventory that may require us to record charges to cost of revenue. Xbox 360 consoles will be assembled in Asia; disruptions in the supply chain may result in console shortages that would affect our revenues and operating margins.

If our goodwill or amortizable intangible assets become impaired we may be required to record a significant charge to earnings.    Under generally accepted accounting principles, we review our amortizable intangible assets for impairment when events or changes in circumstances indicate the carrying value may not be recoverable. Goodwill is required to be tested for impairment at least annually. Factors that may be considered a change in circumstances indicating that the carrying value of our goodwill or amortizable intangible assets may not be recoverable include a decline in stock price and market capitalization, reduced future cash flow estimates, and slower growth rates in our industry. We may be required to record a significant charge to earnings in our financial statements during the period in which any impairment of our goodwill or amortizable intangible assets is determined, negatively impacting our results of operations.

Changes in accounting may affect our reported earnings and operating income.    Generally accepted accounting principles and accompanying accounting pronouncements, implementation guidelines, and interpretations for many aspects of our business, such as revenue recognition for software, accounting for investments, and treatment of goodwill or amortizable intangible assets, are highly complex and involve subjective judgments. Changes in these rules or their interpretation or changes in our products or business could significantly change our reported earnings and operating income and could add significant volatility to those measures, without a comparable underlying change in cash flow from operations. See Note 1 in “Item 8. Financial Statements and Supplementary Data” and “Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations – Critical Accounting Policies” of this report.

We operate a global business that exposes us to additional risks.    We operate in over 100 countries and a significant part of our revenue comes from international sales. Pressure to make our pricing structure uniform might

Item 1A

require that we reduce the sales price of our software in the United States and other countries. Operations outside of the United States may be affected by changes in trade protection laws, policies and measures, and other regulatory requirements affecting trade and investment; unexpected changes in regulatory requirements for software; social, political, labor or economic conditions in a specific country or region; and difficulties in staffing and managing foreign operations. While we hedge a portion of our international currency exposure, significant fluctuations in exchange rates between the U.S. dollar and foreign currencies may adversely affect our net revenues.

General economic and geo-political risks may affect our revenue and profitability.    Inflation, softness in corporate information technology spending, or other changes in general economic conditions that affect demand for computer hardware or software could adversely affect our revenue or our investment portfolio. Abrupt political change, terrorist activity, and armed conflict pose a risk of general economic disruption in affected countries or generally and could require changes in our operations and security arrangements, thus increasing our operating costs. These conditions may lend additional uncertainty to the timing and budget for technology investment decisions by our customers.

Catastrophic events may disrupt our business.    We are a highly automated business and a disruption or failure of our systems in the event of a major earthquake, cyber-attack, terrorist attack, or other catastrophic event could cause delays in completing sales and providing services. Our corporate headquarters, a significant portion of our research and development activities, and certain other critical business operations are located in the Seattle, Washington area, and we have other business operations in the Silicon Valley area of California, both of which are near major earthquake faults. A catastrophic event that results in the destruction or disruption of any of our critical business or information technology systems could severely affect our ability to conduct normal business operations and, as a result, our future operating results could be adversely affected.

Acquisitions and joint ventures may have an adverse effect on our business.    We expect to continue making acquisitions or entering into joint ventures as part of our long-term business strategy. These transactions involve significant challenges and risks including that the transaction does not advance our business strategy, that we don’t realize a satisfactory return on the investment we make, or that we may experience difficulty in the integration of new employees, business systems, and technology, or diversion of management’s attention from our other businesses. These factors could adversely affect our operating results or financial condition.

We have limited insurance.    We maintain third party insurance coverage against various liability risks and risks of property loss. Because of the unavailability or high cost of conventional insurance arrangements, we have entered into captive insurance arrangements for the purpose of protecting against possible catastrophic and other risks not covered by traditional insurance markets. As of June 30, 2006, the face value of captive insurance arrangements was $2.0 billion. Actual value at any particular time will vary due to deductibles, exclusions, other restrictions, and claims. While we believe these arrangements are an effective way to insure against liability and property damage risks, the potential liabilities associated with the risks discussed in this report or other events could exceed the coverage provided by such arrangements.

Improper disclosure of personal data could result in liability and harm our reputation.    We store and process significant amounts of personally identifiable information as we offer a large array of products and services to our customers. It is possible that our security controls over personal data, our training of employees and vendors on data security, and other practices we follow may not prevent the improper disclosure of personally identifiable information. Such disclosure could harm our reputation and subject us to liability under laws that protect personal data, resulting in increased costs or loss of revenue. Our software products also enable our customers to store and process personal data. Perceptions that our products do not adequately protect the privacy of personal information could inhibit sales of our products.

Other risks that may affect our business.    Other factors that may affect our performance may include:

We have received no written comments regarding our periodic or current reports from the staff of the SEC that were issued 180 days or more preceding the end of our fiscal year 2006 that remain unresolved.

 ITEM 2.    PROPERTIES

Our corporate offices consist of approximately 11.0 million square feet of office building space located in King County, Washington: 8.5 million square feet of owned space that is situated on approximately 500 acres of land we own in our corporate campus and approximately 2.5 million square feet of space we lease. We own approximately 533,000 square feet of office building space domestically (outside of the Puget Sound corporate campus) and lease many sites domestically totaling approximately 2.7 million square feet of office building space.

We occupy many sites internationally, totaling approximately 6.9 million square feet that is leased and approximately 883,000 square feet that is owned. These facilities include our European Operations Center that leases a 187,000 square foot campus in Dublin, Ireland, a 56,000 square foot disk duplication facility in Humacao, Puerto Rico, and a 159,000 square foot facility in Singapore for our Asia Pacific Operations Center and Regional headquarters. Leased office building space includes the following locations: Tokyo, Japan 408,000 square feet; Unterschleissheim, Germany 381,000 square feet; Les Ulis, France 262,000 square feet; Reading, England 241,000 square feet; and Mississauga, Canada 161,000 square feet. In addition to the above locations, we have various product development facilities, both domestically and internationally, as described in “Operations” above.

Our facilities are fully used for current operations of all segments, and suitable additional space is available to accommodate expansion needs. We own 63 acres of land in Issaquah, Washington, which can accommodate 1.2 million square feet of office space and we have an agreement with the City of Redmond under which we may develop an additional 2.2 million square feet of facilities at our campus in Redmond, Washington.

 ITEM 3.    LEGAL PROCEEDINGS

On May 22, 2006, the Korean Fair Trade Commission (“KFTC”) denied our motion for reconsideration of the formal written ruling against us in its competition law investigation of the company. As part of its decision, however, the KFTC dropped the requirement prohibiting us from including Windows Media Player or Windows Messenger, or any feature with similar functionality, in any product other than the Windows client operating system for which we have a 50% or greater market share. Our request to stay the KFTC corrective order was denied on July 31, 2006. Our appeal of the KFTC’s decision to the Seoul High Court is still pending.

On July 12, 2006, the European Commission announced its determination that we had not complied with the technical documentation requirements in its 2004 Decision against us, and levied a fine of €281 million ($351 million). We intend to appeal this fine to the Court of First Instance. We have completed the written and oral procedures in our appeal of the Commission’s underlying March 2004 decision finding Microsoft in violation of European competition law and accompanying €497 million ($605 million) fine and are awaiting a decision by the Court of First Instance.

FINANCIAL CONDITION AND RESULTS OF OPERATIONS

RESULTS OF OPERATIONS FOR FISCAL YEARS 2006, 2005, AND 2004

OVERVIEW

The following Management’s Discussion and Analysis (“MD&A”) is intended to help the reader understand the results of operations and financial condition of Microsoft Corporation. MD&A is provided as a supplement to, and should be read in conjunction with, our financial statements and the accompanying notes to the financial statements (“Notes”).

We develop, manufacture, license, and support a wide range of software products for many computing devices. Our software products include operating systems for servers, PCs, and intelligent devices; server applications for distributed computing environments; information worker productivity applications; business solutions applications; and software development tools. We provide consulting and product support services, and we train and certify system integrators and developers. We sell the Xbox video game console and games, PC games, and PC peripherals. Online communication and information services are delivered through our MSN portals and channels around the world.

Our revenue historically has fluctuated quarterly and has generally been the highest in the second quarter of our fiscal year due to corporate calendar year-end spending trends in our major markets and holiday season spending by consumers. Our Home and Entertainment segment is particularly subject to seasonality as its products are aimed at the consumer market and are in highest demand during the holiday shopping season. Typically, Home and Entertainment has generated over 40% of its yearly segment revenues in our second fiscal quarter. We believe the seasonality of revenue is likely to continue in the future.

We intend to sustain the long-term growth of our businesses through technological innovation, engineering excellence, and a commitment to delivering high-quality products and services to customers and partners. Recognizing that one of our primary challenges is to help accelerate worldwide PC adoption and software upgrades, we continue to advance the functionality, security, and value of Windows operating systems. We also are increasing our focus on emerging markets and reducing the amount of unlicensed software in those markets. In addition, we continue to develop innovative software applications and solutions that we believe will enhance the productivity of information workers, improve communication and collaboration in work groups, aid business intelligence, and streamline processes for small and mid-sized businesses. To sustain the growth of our Server and Tools business amid competition from other vendors of both proprietary and open source software, our goal is to deliver products that provide the best platform for network computing – the easiest to deploy and manage and most secure – with the lowest total cost of ownership.

We continue to invest in research and development in existing and new lines of business, including business solutions, mobile computing, communication, entertainment, and others that we believe may contribute to our long-term growth. We also research and develop advanced technologies for future software products. We believe that delivering innovative and high-value solutions through our integrated platform is the key to meeting customer needs and to our future growth.

We believe that over the last few years we have laid a foundation for long-term growth by delivering innovative products, creating opportunities for partners, improving customer satisfaction with key audiences, putting some of our most significant legal cases behind us, and improving our internal business processes. Our focus in fiscal year 2007 is building on this foundation and executing well in key areas, including continuing to innovate on our integrated software platform, responding effectively to customer and partner needs, and continuing to focus internally on product excellence, business efficacy, and accountability across the company.

Key market opportunities include:

Item 7

Worldwide macroeconomic factors have a strong correlation to business and consumer demand for our software, services, games and Internet service offerings. We expect a broad continuation in the economic conditions and demand in fiscal year 2007 as compared to fiscal year 2006.

As open source software development and distribution evolves, we continue to seek to differentiate our products from competing products that are based on open source software. We believe that Microsoft’s share of server unit operating systems increased in fiscal year 2006.

Summary of Results for Fiscal Years 2006, 2005, and 2004

Our revenue growth for fiscal year 2006 was driven primarily by growth in SQL Server following the launch of SQL Server 2005 in the second quarter, Windows Server and other server applications, increased Xbox revenue resulting from the Xbox 360 launch in the second quarter, growth in licensing of Windows client operating systems through OEMs, and increased licensing of Office and other Information Worker products. Based on our estimates, total worldwide PC shipments from all sources grew approximately 12% to 14% and total server hardware shipments grew approximately 11% to 13% during fiscal year 2006. Foreign currency exchange rates did not have a significant impact on consolidated or operating segment revenue during the fiscal year.

Revenue growth for fiscal year 2005 was driven by growth in licensing of Windows Server operating systems and other server applications, licensing of Windows client operating systems through OEMs, and increased licensing of Office and other Information Worker products. The November 2004 launch of the “Halo 2” Xbox game also contributed to overall revenue growth for the company. Total worldwide PC shipments from all sources grew approximately 11% to 13% and total server hardware shipments grew approximately 13% to 14% during fiscal year 2005 as compared to fiscal year 2004. The net impact of foreign exchange rates on revenue was positive in 2005, primarily due to relative strengthening of most foreign currencies, particularly the euro and Japanese yen, against the U.S. dollar. Partially offsetting revenue growth rates was a $1.08 billion decline in earned revenue from Upgrade Advantage in fiscal year 2005. This revenue was recognized over fiscal year 2003 and fiscal year 2004 and in the first quarter of fiscal year 2005 when the contract period expired. Fiscal year 2004 revenue growth was primarily driven by the growth in licensing of Windows client operating systems through OEMs, Windows Server operating systems, Office and other server applications as a result of growth in PC and server hardware shipments. The worldwide PC shipment growth rate from all sources was estimated at 13% and the Windows server shipment was estimated at 18% in fiscal year 2004 as compared to fiscal year 2003. The net impact of foreign exchange rates on revenue was positive in fiscal year 2004 due to a relative strengthening of most foreign currencies versus the U.S. dollar. This resulted in approximately $1.10 billion growth in total revenue.

Operating income for fiscal year 2006 increased primarily reflecting the revenue increase and a $991 million decrease in costs for legal settlements and legal contingencies. These changes were partially offset by a $1.62 billion increase in cost of revenue primarily related to Xbox 360 and a $1.26 billion increase in sales and marketing expense primarily as a result of increased investments in partner marketing and product launch-related spending. Headcount-related costs, including stock-based compensation expense, increased $682 million or 7% resulting from both an increase in salaries and benefits for existing headcount and a 16% growth in headcount over the past twelve months. Stock-based compensation expense decreased $733 million or 30% reflecting a continuing decline in stock option amortization expense.

Operating income increased in fiscal year 2005 due to a decline in stock-based compensation expense; increased revenue in Server and Tools, Client and Information Worker, which have higher gross margins as compared to other segments; and a reduction in legal costs associated with major litigation. In addition, strong sales of Halo 2 reduced the overall operating loss for the Home and Entertainment segment for fiscal year 2005. The $3.29 billion decrease in stock-based compensation expense was partially offset by increased operating expenses of $562 million related to increased salary and benefits for new and existing headcount. General and administrative expenses related to major litigation declined in fiscal year 2005 due to the $2.53 billion of charges related to the settlement of Sun

Item 7

Microsystems litigation and the fine imposed by the European Commission in fiscal year 2004. This effect was partially offset by legal expenses of $2.08 billion related to settlements with IBM, Novell, Gateway, and end-user class action plaintiffs to resolve antitrust issues and other matters. In fiscal year 2004, the operating income decline was caused primarily by $2.53 billion of legal charges and $2.21 billion of stock-based compensation expense related to our employee stock option transfer program, mainly offset by an increase in revenue.

We implemented changes in employee compensation in fiscal year 2004 whereby employees are granted stock awards rather than stock options. We also completed an employee stock option transfer program in the second quarter of fiscal year 2004 in which employees could elect to transfer all of their vested and unvested stock options with a strike price of $33.00 or higher to JPMorgan Chase Bank (“JPMorgan”). The unvested options that were transferred to JPMorgan became vested upon the transfer. A total of 345 million of the 621 million eligible options were transferred, which resulted in additional stock-based compensation expense of $2.21 billion in the second quarter of fiscal year 2004. As a result of these changes, stock-based compensation expense decreased in fiscal years 2006 and 2005, and we expect stock-based compensation expense related to stock options to continue to decrease in fiscal year 2007.

Fiscal Year 2007 Outlook

In fiscal year 2007, we expect continued double digit revenue growth primarily as a result of the upcoming launches of Windows Vista and the 2007 Microsoft Office system. We estimate worldwide PC shipments will grow between 8% and 10%. We expect that PC unit growth rates will be higher in the consumer segment than in the business segment and higher in emerging markets than in mature markets. We estimate worldwide server unit shipments will grow between 10% and 12% in fiscal year 2007 as compared to fiscal year 2006. We do not expect a significant impact from year-over-year foreign currency exchange rates in fiscal year 2007.

We expect our operating income growth rate to lag our revenue growth rate in the first half of fiscal year 2007 due to an increasing mix of Xbox 360 console revenue and related costs, coupled with significant investments in preparation for the launches of our flagship products. We expect this trend to reverse in the second half of the fiscal year when we expect operating income to grow faster than revenue.

SEGMENT PRODUCT REVENUE/OPERATING INCOME (LOSS)

Our seven segments were Client; Server and Tools; Information Worker; Microsoft Business Solutions; MSN; Mobile and Embedded Devices; and Home and Entertainment. On July 17, 2006, we announced a change in our operating segments reflecting the culmination of our realignment announced in September 2005. These changes will be effective for fiscal year 2007; the seven segments discussed in this analysis are presented the way we internally managed and monitored performance at the business group level in fiscal years 2006, 2005, and 2004.

The revenue and operating income/(loss) amounts in this section are presented on a basis consistent with U.S. Generally Accepted Accounting Principles (“GAAP”) and include certain reconciling items attributable to each of the segments. The segment information appearing in Note 18 – Segment Information of the Notes to Financial Statements is presented on a basis consistent with the Company’s internal management reporting, in accordance with Statement of Financial Accounting Standards (“SFAS”) No. 131, Disclosures about Segments of an Enterprise and Related Information. Certain corporate level expenses have been excluded from our segment operating results and are analyzed separately. Fiscal years 2005 and 2004 amounts have been restated for certain internal reorganizations and to conform to the fiscal year 2006 presentation.

Client

Table of Contents

 Part II 

Item 7

Client consists of premium edition operating systems, including Windows XP Professional, Media Center Edition, Tablet PC Edition, and other standard Windows operating systems, including Windows XP Home. Premium offerings are Windows operating systems sold at a premium above Windows XP Home. Client revenue growth correlates with the growth of purchases of PCs from OEMs that pre-install versions of Windows operating systems because the OEM channel accounts for over 80% of total Client revenue.

Client revenue increased in fiscal year 2006 reflecting $1.18 billion or 12% growth in OEM revenue driven by 17% growth in OEM license units from increased PC unit shipments, partially offset by a $118 million or 6% decrease in revenue from commercial and retail licensing of Windows operating systems. During the year, the mix of OEM Windows operating systems licensed with premium edition operating systems as a percentage of total OEM Windows operating systems licensed (“OEM Premium Mix”) increased two percentage points to 52%. OEM revenue growth included an increase to revenue of $89 million resulting from the alignment of our billings associated with OEM distributors in our system builder channel with both industry standards and other Microsoft channels. The differences between unit growth rates and revenue growth rates from year to year are affected by changes in the OEM Premium Mix, changes in the geographical mix, and the channel mix of products sold by large, multi-national OEMs versus those sold by local and regional system builders. Client revenue increased in fiscal year 2005 driven by 12% growth in OEM license units and $886 million or 10% growth in OEM revenue from increased PC unit shipments, partially offset by a $198 million or 9% decrease in revenue from commercial and retail licensing of Windows operating systems. The OEM Premium Mix remained flat at 50% of total OEM Windows operating systems as compared to the previous year. Revenue earned from Upgrade Advantage declined by $99 million in fiscal year 2005 contributing to the decrease in commercial and retail licensing revenue.

Client operating income increased in fiscal year 2006 reflecting the increase in OEM revenue partially offset by a $224 million increase in sales and marketing expenses, excluding headcount-related costs, mainly driven by increased investments in partner marketing and Windows Vista pre-launch programs. Headcount-related costs increased 6% in fiscal year 2006 reflecting both a 13% increase in headcount primarily associated with Windows Vista and further investments in our sales and marketing organization, and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. Client operating income increased in fiscal year 2005 primarily due to an increase in OEM revenue and a $444 million decrease in stock-based compensation expense. These factors were partially offset by an increase in sales and marketing expenses associated with “Start Something,” a globally launched advertising campaign, marketing for security initiatives, and an increase in salary and benefits for new and existing headcount. The additional headcount for research and development was primarily devoted to the continued development of Windows Vista.

Server and Tools

Server and Tools consists of server software licenses and client access licenses (“CAL”) for Windows Server, Microsoft SQL Server, Exchange Server and other server products. It also includes developer tools, training, certification, Microsoft Press, Premier and Professional product support services, and Microsoft Consulting Services. Server and Tools concentrates on licensing products, applications, tools, content and services that make information technology professionals and developers more productive and efficient. The segment uses multiple channels for licensing including pre-installed OEM versions, licenses through partners, and licenses directly to end customers. The licenses are sold both as one-time licenses and as multi-year volume licenses. Server and Tools uses product innovation and partnerships with information technology professionals to drive the adoption and sales growth of its products.

Server and Tools revenue increased during fiscal year 2006 mainly driven by growth in SQL Server, Windows Server, and Core CAL. SQL Server 2005 and Visual Studio 2005 were launched in the second quarter of fiscal year 2006 and produced revenue growth in these product lines. Revenue is impacted by overall server hardware shipments which we estimate grew 11% to 13% in fiscal year 2006. Server and Server applications revenue, including CAL revenue, and developer tools, training and certification revenue grew $1.31 billion or 16% during fiscal year 2006. The results reflect broad adoption of Windows Server products, especially SQL Server, which grew over 30% for

the year. Consulting, Premier and Professional product support services revenue increased $218 million or 15% primarily due to higher demand for services. In fiscal year 2005, Server and Server application revenue, including CAL revenue, grew $1.10 billion or 17%. Consulting, Premier, and Professional product support services revenue increased $241 million or 19% compared to the previous year. Foreign currency exchange rate changes accounted for $284 million or three percentage points of total Server and Tools revenue growth, which was offset by a $314 million decline in Upgrade Advantage revenue earned.

Server and Tools operating income increased during fiscal year 2006 primarily reflecting increased revenue, partially offset by increased sales and marketing expenses. Excluding headcount-related costs, sales and marketing expenses increased $274 million due to additional spending to support long-term strategies and marketing expenses primarily related to the launch of SQL Server 2005 and Visual Studio 2005. Total Server and Tools headcount-related costs increased 5% related to both an 11% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. In fiscal year 2005, Server and Tools operating income increased primarily due to increased revenue and a $1.07 billion decrease in stock-based compensation expense. This increase was partially offset by an increase in sales and marketing costs and headcount-related costs as a result of increased headcount and an increase in salaries and benefits for existing headcount.

Information Worker

Information Worker primarily consists of the Microsoft Office system of programs, servers, solutions, and services designed to increase personal, team, and organization productivity. Information Worker includes Microsoft Office, Microsoft Project, Microsoft Visio, SharePoint Portal Server CAL, and other information worker products including Office Communications Server and OneNote. Revenue growth depends on the ability to add value to the core Office product set and expand our product offerings in other information worker areas such as enterprise content management, collaboration, unified communications, and business intelligence.

Information Worker revenue increased in fiscal year 2006 primarily reflecting a $521 million or 5% increase in volume licensing, retail packaged products, and preinstalled versions of Office in Japan, while OEM revenue increased $66 million or 4%. Information Worker revenue increased in fiscal year 2005 primarily reflecting a $269 million or 3% increase in volume licensing, retail packaged product, and pre-installed versions of Office in Japan, a $91 million or 6% increase in OEM revenue, and the impact of foreign currency exchange rates, partially offset by reduced Upgrade Advantage earned revenue. Changes in foreign currency exchange rates accounted for approximately $367 million or three percentage points of the revenue growth for fiscal year 2005, offset by a $663 million decline in Upgrade Advantage earned revenue.

Information Worker operating income increased in fiscal year 2006 primarily due to the revenue growth, partially offset by a $283 million or 15% increase in sales and marketing expenses related to supporting field sales efforts and a $71 million or 10% increase in research and development expenses. Headcount-related costs increased 14% during fiscal year 2006 reflecting both an 18% increase in headcount related to supporting field sales efforts and research and development investments in future products and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. Information Worker operating income growth for fiscal year 2005 was primarily due to the revenue growth and a $304 million decrease in stock-based compensation expense. Operating expenses were also impacted by a reduction in marketing campaign costs from the previous period associated with the launch of Office 2003. This decline was offset by an increase in headcount-related costs as a result of an increase in headcount and an increase in salaries and benefits for existing headcount.

Microsoft Business Solutions

Microsoft Business Solutions provides business management software solutions targeted to businesses of varying sizes. The main products consist of enterprise resource planning (“ERP”) solutions, customer relationship management (“CRM”) software, retail solutions, Microsoft Partner Program (“MSPP”), and related services. Microsoft Business Solutions also includes the Small and Mid-market Solutions and Partners (“SMS&P”), which focuses on sales to customers and partners in the small and mid-market customer segments. Revenue is derived from software and services sales, with software sales representing a significant amount of total revenue. Software revenues include both new software licenses and enhancement plans, which provide customers with future software upgrades over the period of the plan. Our solutions are delivered through a worldwide network of channel partners that provide services and local support.

Microsoft Business Solutions revenue increased in fiscal year 2006 driven by new users for Microsoft CRM and existing Dynamics ERP customers purchasing functionality and user licenses. The increase in Microsoft Business Solutions revenue in fiscal year 2005 was mainly due to 10% revenue growth in software partially offset by 25% decline in services revenue. The software revenue increase was driven by 9% growth in license revenue and 16% growth in enhancement revenue and was attributed to growth in ERP and CRM solutions and an increase in MSPP subscriptions.

Microsoft Business Solutions operating income increased in fiscal year 2006 reflecting the increase in revenue accompanied by a $56 million decrease in sales and marketing expense as a result of decreased net SMS&P spending. Headcount-related costs increased 3% reflecting both a 10% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. Microsoft Business Solutions operating loss declined in fiscal year 2005 primarily due to a $175 million decline in stock-based compensation expense, an increase in product revenue, and a decline in amortization of acquired intangibles. The reduction in operating loss was partially offset by a net increase in sales and marketing expense driven by incremental costs in the SMS&P organization. In addition, we increased our marketing and product development spending in our ERP and CRM portfolios.

MSN

MSN includes personal communications services, such as e-mail and instant messaging, and online information offerings, such as MSN Search, and the MSN portals and channels around the world. MSN also provides a variety of online paid services in addition to MSN Internet Access and MSN Premium Web Services. Revenue is derived primarily from advertisers on MSN, from consumers and partners through subscriptions and transactions generated from online paid services, and from MSN narrowband Internet access subscribers. In fiscal year 2006, we launched MSN adCenter – our internally developed advertising platform – in certain international markets and throughout the U.S. where it now serves 100 percent of paid search traffic on our online properties. We believe MSN adCenter will enable us to increase both display and search advertising revenues by reducing our reliance on third parties for delivering ads. Effective July 1, 2005, functions related to MapPoint previously reported in Mobile and Embedded

Devices were moved to MSN. Mobile and Embedded Devices and MSN operating results for the prior periods have been restated for this reorganization. We announced in fiscal year 2006, Windows Live™, a set of Internet services and software designed to improve the users’ connected experience, including Windows Live™ Local and Windows Live Messenger.

MSN revenue decreased in fiscal year 2006 primarily reflecting a $195 million or 28% decline in access revenue, partially offset by a $126 million or 9% increase in advertising revenue and a $23 million or 9% increase in revenue from subscription and transaction services other than access. As of June 30, 2006, MSN had 2.1 million access subscribers compared with 2.7 million at June 30, 2005. In addition, MSN had over 261 million active Hotmail accounts and over 243 million active Messenger accounts as of June 30, 2006. The increase in advertising revenue reflects growth in display advertising for portals, channels, email, and messaging services, which was partially offset by a decline in search revenue due to the transition to adCenter. In fiscal year 2005, MSN revenue increased reflecting $193 million or 16% growth in advertising revenue primarily as a result of industry and market growth and continued growth of MSN display advertising revenue and $84 million or 88% growth in subscription and transaction services revenue. These increases were partially offset by the search clarity in advertising program, the impact of the homepage redesign, and a decline of $219 million or 24% in access revenue, driven by the continued migration of Internet Access subscribers to broadband or other competitively priced Internet service providers.

MSN operating income decreased in fiscal year 2006 due to a $230 million or 39% increase in research and development costs, a $126 million or 22% increase in sales and marketing expenses, and a $67 million or 9% increase in cost of revenue as we continue to invest in MSN adCenter, Windows Live, and other new platforms. Headcount-related costs increased 25% reflecting a 44% increase in headcount and increased salaries and benefits for existing employees, partially offset by a decrease in stock-based compensation. In fiscal year 2005, MSN operating income increased mainly due to a $241 million decrease in stock-based compensation expense, reduced costs associated with the Internet Access business, and increased advertising and subscription revenue. Partially offsetting the decreased expenses were increased headcount-related costs as a result of increased headcount and an increase in salaries and benefits for existing headcount.

Mobile and Embedded Devices

* Not meaningful

Mobile and Embedded Devices includes Windows Mobile software, Windows Embedded operating systems, and Windows Automotive. These products extend the advantages of the Windows platform to mobile devices such as PDAs, phones, and a wide range of embedded devices. The business is also responsible for managing sales and customer relationships for Microsoft overall with device manufacturers and communication sector customers. The communication sector includes network service providers (such as wireless, wireline and cable operators) and media and entertainment companies. The market for products in these segments is intensely competitive. Competitive alternatives vary based on product lines and include product offerings from commercial and non-commercial mobile operating system providers, and proprietary software developed by OEMs and mobile operators. Effective July 1, 2005, functions related to MapPoint previously reported in Mobile and Embedded Devices were moved to MSN. Mobile and Embedded Devices and MSN operating results for the prior periods have been restated for this reorganization.

Mobile and Embedded Devices revenue increased in fiscal year 2006 primarily due to unit volume increases in major product lines, especially Windows Mobile software sales and Windows Embedded operating systems. Increased revenue for Windows Mobile software was primarily driven by increased market demand for phone-enabled devices, partially offset by a decline in shipments for stand-alone PDAs. In fiscal year 2006, revenue for Windows Mobile software increased $55 million or 37% while revenue for Windows Embedded operating systems increased $49 million or 47%, which was primarily due to the product being included in new product designs for both new and existing customers. Unit volume increases in major product lines drove revenue growth for fiscal year 2005 over fiscal

year 2004, primarily driven by increased market demand for phone-enabled devices, and increased growth in shipments for standalone PDAs. In fiscal year 2005, revenue for Windows Mobile software increased $46 million or 45% and revenue for Windows Embedded operating systems increased $19 million or 21%. Unit volume increases in major product lines drove revenue growth for fiscal year 2005 over fiscal year 2004, primarily driven by increased market demand for phone-enabled devices, and increased growth in shipments for standalone PDAs.

Mobile and Embedded Devices generated operating income for fiscal year 2006 as opposed to the operating loss in fiscal year 2005 primarily due to increased revenue, partially offset by a $42 million or 21% increase in both research and development and general and administrative expenses. Headcount-related costs increased 15% reflecting both a 24% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. The operating loss for fiscal year 2005 decreased compared to fiscal year 2004 primarily due to a $95 million decrease in stock-based compensation, as well as the growth in revenue and a decrease in sales and marketing expense. This improvement was partially offset by increased salary and benefit costs from increased headcount, and increased investment in research and development.

Home and Entertainment

Home and Entertainment includes the Microsoft Xbox video game console system, PC games, CPxG (consumer software and hardware products), and TV platform products for the interactive television industry. The success of video game consoles is determined by console innovation, the portfolio of video game content for the console, online offerings, and the market share of the console. Our Xbox business is transitioning to a new console, the Xbox 360, which launched in the second quarter of fiscal year 2006. We believe that the functionality of our new console, games portfolio, and online offerings are well-positioned relative to forthcoming competitive consoles. We also believe launching in advance of competitive consoles will provide a strategic advantage for the long-term success of Xbox 360. Revenue from the first generation of Xbox products has declined and is expected to continue to decline as a result of the introduction of Xbox 360.

Home and Entertainment revenue increased in fiscal year 2006 primarily due to the launch of the Xbox 360 console partially offset by a decline in first party Xbox game sales primarily resulting from the significant impact of Halo 2 in fiscal year 2005. We sold approximately 5 million Xbox 360 consoles during fiscal year 2006. The revenue growth was also attributable to $140 million or 15% growth from our other product lines, primarily as a result of an increase in PC games sales due to significant new game releases, especially “Age of Empires III”, and an increase in MSTV revenue due to deployments in fiscal year 2006. Revenue increased in fiscal year 2005 primarily due to significant new product launches, which resulted in a $416 million or 23% increase in Xbox revenue. Halo 2 was introduced in the second quarter of fiscal year 2005 and generated over $300 million in revenue in fiscal year 2005. Revenue from consumer hardware and software, PC games, and TV platforms declined $50 million or 5% compared to fiscal year 2004 due to lower PC games software sales.

Home and Entertainment operating loss increased in fiscal year 2006 primarily as a result of a $1.64 billion increase in cost of revenue resulting from the number of Xbox 360 consoles sold and higher Xbox 360 unit costs, partially offset by the revenue growth. Our fiscal year 2006 operating loss increased due to the significant impact of Halo 2 in fiscal year 2005. Headcount-related costs increased 5% reflecting both a 19% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. The fiscal year 2005 operating loss decreased primarily due to an increase in high margin Xbox software sales, lower Xbox console units costs, a $90 million lower-of-cost-or-market inventory adjustment recorded in fiscal year 2004, and a $219 million decrease in stock-based compensation expense. The decrease was partially offset by an increase in costs associated with Xbox 360 console development and related launch efforts.

Corporate-Level Activity

Certain corporate-level expenses are not allocated to our segments. Those expenses primarily include corporate operations related to broad-based sales and marketing, product support services, human resources, legal, finance, information technology, corporate development and procurement activities, research and development and other costs, and legal settlements and contingencies.

Corporate-level expenses decreased in fiscal year 2006, primarily reflecting a $991 million decrease in costs for legal settlements and legal contingencies partially offset by an $84 million increase in headcount-related costs. We incurred $1.32 billion in legal charges during fiscal year 2006 including settlement expense of $361 million related to our settlement with RealNetworks, Inc. as well as other intellectual property and antitrust matters, and the €281 million ($351 million) fine imposed by the European Commission in July 2006 related to its 2004 decision in its competition law investigation of Microsoft, as compared to $2.31 billion in legal charges incurred during the prior year primarily related to settlements with Novell, Inc., Gateway, IBM, and other antitrust and competition law matters. Headcount-related costs increased 5% during the twelve months ended June 30, 2006 reflecting both a 23% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation.

Corporate-level expenses decreased in fiscal year 2005, primarily as a result of a $736 million reduction in stock-based compensation expense and decreased costs for legal settlements and legal contingencies. In fiscal year 2005, we recognized $2.31 billion in legal charges as compared to $2.53 billion in fiscal year 2004 which included a $1.92 billion charge for a settlement with the Sun Microsystems, Inc., and the fine of €497 million ($605 million) imposed by the European Commission.

Change to Financial Reporting Structure

On July 17, 2006, we announced that effective the first quarter of fiscal year 2007, we will report our businesses under five operating segments, reflecting completion of the previously announced changes in our organizational structure and how we will manage our business beginning in fiscal year 2007. Each of the five segments will be organized under one of the three operating divisions announced earlier in fiscal year 2006:

The five operating segments are described below. The first three of these will comprise the Platforms and Services Division.

Client    will include the former Client segment. Products will include Windows XP Professional and Home, Media Center Edition, Tablet PC Edition, and other standard Windows operating systems.

Server and Tools    will include the former Server and Tools segment, excluding the Exchange Server business and certain client access licenses related to products residing in the Microsoft Business Division. Products will include the Windows Server operating system, Microsoft SQL Server, Microsoft Consulting Services, product support services, Visual Studio, System Center products, the Forefront security family of products, and Biz Talk Server, among others.

Online Services Business    will include the former MSN segment and Windows Live. Products will include MSN Search, MapPoint, MSN Internet Access, MSN Premium Web Services, MSN Mobile Services, and Windows Live.

Microsoft Business Division    will include the former Information Worker and Microsoft Business Solutions segments, as well as the Exchange Server business and certain client access licenses, formerly included in the Server and Tools segment. Products will include Microsoft Office, Microsoft Project, Microsoft Visio, SharePoint Portal Server CAL, Microsoft Live Meeting, One Note, Office Communication Server, Microsoft Dynamics AX, Microsoft

Item 7

Dynamics CRM, Microsoft Dynamics GP, Microsoft Dynamics NAV, Microsoft Dynamics SL, Microsoft Dynamics Retail Management System, Microsoft Partner Program, and Microsoft Office Small Business Accounting.

Entertainment and Devices Division    will include the former Home and Entertainment and Mobile and Embedded Devices segments. Products will include Xbox 360, Xbox, Xbox Live, CPxG (consumer software and hardware products), IPTV, Windows Mobile software platform, Windows Embedded device operating system, and Windows Automotive.

Our historical results under this new segmentation for the four quarters in fiscal years 2006 and 2005 were as follows:

Revenue

Operating Income / (Loss)

Our outlook for fiscal year 2007 based on the five operating segments is as follows:

Client    We expect revenue to grow reflecting improvement in the commercial and retail portion of the business due to our upcoming launch of Windows Vista. We expect revenue generated from OEMs to grow slower than the PC hardware market due to increased concentration among larger OEMs, consumer hardware shipments growing faster than business shipments, and relatively faster growth in emerging markets. We expect PC shipments to grow 8% to 10% for fiscal year 2007. We believe that PC unit growth rates will be higher in the consumer segment than in the business segment and higher in emerging markets than in mature markets.

Server and Tools    We expect continued momentum from recent product launches and the expansion of our products in security, management and designer tools will help drive our overall revenue growth in fiscal year 2007. We estimate overall server hardware unit shipments will grow 10% to 12% in fiscal year 2007. However, we face competition from Linux-based, Unix, and other server operating systems as well as competition in server applications.

Item 7

Online Services Business    We expect increased growth in display advertising revenue as the portals, channels, and communications services continue to expand globally and the overall Internet advertising industry continues to expand. Our search revenue is expected to grow in fiscal year 2007 as a result of continued ramp up of adCenter. We expect revenue from narrowband Internet Access to continue to decline in fiscal year 2007.

Microsoft Business Division    We expect Microsoft Business Division revenue to grow in fiscal year 2007. We feel that our customers’ continued preference to purchase annuity contracts indicates enthusiasm for the 2007 Microsoft Office system. We also expect continued demand for our Dynamics products, building on the fiscal 2006 momentum.

Entertainment and Devices Division    We expect revenue to increase from fiscal year 2006 due to the increased availability of the Xbox 360 console unit during the entire fiscal year, including the second holiday season after the launch in fiscal year 2006. In fiscal year 2007, we expect to introduce a music and entertainment device, the first in a new family of hardware and software products for the consumer market. The availability of a commercial IPTV product is expected to drive significant growth in MSTV revenue across several geographies. Revenue from existing mobility and embedded devices is expected to increase due to unit volume increases of Windows Mobile software driven by increased market demand for phone-enabled devices and Windows Embedded operating systems. Short product life cycles in product lines such as Windows Mobile software may impact our continuing revenue streams. Xbox 360 console unit costs are expected to decline.

As we implement our long-term growth strategy, we expect to increase our level of spending in four key areas in fiscal year 2007: increased product costs associated with Xbox consoles; marketing and field sales spending including launch costs; quickening the pace of development in growth areas such as business intelligence, security, management and unified communications (including acquisitions); and increased costs to execute on our online services strategy. While these investments will translate into increased operating expenses in fiscal year 2007, we believe they will help lay the groundwork for future growth and profitability.

Operating Expenses

Cost of Revenue

Cost of revenue includes manufacturing and distribution costs for products sold and programs licensed, operating costs related to product support service centers and product distribution centers, costs incurred to support and maintain Internet-based products and services, and costs associated with the delivery of consulting services. Cost of revenue in fiscal year 2006 increased mainly due to a $1.64 billion increase in Home and Entertainment as a result of an increase in the number of total Xbox consoles sold and higher Xbox 360 unit costs. Cost of revenue in fiscal year 2005 decreased due to a $363 million decrease in stock-based compensation expense, a $140 million reduction in costs associated with a decrease in the MSN Internet Access subscriber base, and a $169 million reduction in other product costs mainly due to Xbox consoles cost efficiency, partially offset by increased costs in product support and consulting services costs.

Research and Development

Research and development expenses include payroll, employee benefits, stock-based compensation expense, and other headcount-related costs associated with product development. Research and development expenses also

Item 7

include third-party development and programming costs, localization costs incurred to translate software for international markets, and the amortization of purchased software code and services content. Research and development costs increased during fiscal year 2006 primarily due to increased development costs associated with new and upcoming offerings such as MSN adCenter, the 2007 Microsoft Office system, Windows Vista, Xbox 360, and corporate research activities. Headcount-related costs increased 3% during fiscal year 2006 reflecting both a 17% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. Our research and development expenses decreased in fiscal year 2005 due to a $1.88 billion decrease in stock-based compensation expense. This expense decline was partially offset by increased headcount and product development costs associated with the Xbox 360 console and related games, SQL Server 2005, Windows Vista, and product development in Mobile and Embedded Devices.

Sales and Marketing

Sales and marketing expenses include payroll, employee benefits, stock-based compensation expense and other headcount-related costs associated with sales and marketing personnel and advertising, promotions, trade shows, seminars, and other programs. Sales and marketing expenses increased during fiscal year 2006 primarily due to increased headcount-related costs, investments in partner marketing and product launch-related spending. Headcount-related costs increased 13% during fiscal year 2006 reflecting both a 20% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense.

For fiscal year 2005, sales and marketing expense increased slightly due to $470 million higher headcount-related costs from increased headcount and general salary increases; higher sales and marketing costs driven by product planning, reseller marketing, and advertising campaign costs mainly related to launch of the “Start Something” campaign; launch of “Halo 2”; and launch arrangements for Xbox 360. The increase was offset mainly by a $660 million decrease in stock-based compensation expense.

General and Administrative

General and administrative costs include payroll, employee benefits, stock-based compensation expense and other headcount-related costs associated with finance, legal, facilities, certain human resources, other administrative headcount, and legal and other administrative fees. General and administrative costs decreased in fiscal year 2006 primarily reflecting decreased costs for legal settlements and legal contingencies. We incurred $1.32 billion in legal charges during fiscal year 2006 as compared to $2.31 billion in legal charges incurred during fiscal year 2005. Headcount-related costs increased 7% during the twelve months ended June 30, 2006 reflecting both an 18% increase in headcount and an increase in salaries and benefits for existing headcount, partially offset by a decrease in stock-based compensation expense. General and administrative costs decreased in fiscal year 2005 primarily reflecting decreased stock-based compensation expense and decreased costs for legal settlements and legal contingencies. In fiscal year 2005, we recognized $277 million of stock-based compensation expense as compared to $664 million in fiscal year 2004. In fiscal year 2005, we recognized $2.31 billion in legal charges as compared to $2.83 billion in fiscal year 2004.

Investment Income and Other

The components of investment income and other were as follows:

For fiscal year 2006, dividends and interest income increased due to higher interest rates received on our fixed-income investments, partially offset by a decline in the average balance of dividend and interest-bearing investments as a result of the $32.64 billion special dividend paid on December 2, 2004, and stock repurchases made throughout fiscal year 2006. Dividends and interest income declined $432 million in fiscal year 2005 due to the combination of a greater allocation of funds to lower yielding, more liquid asset classes in preparation for the $32.64 billion special dividend paid on December 2, 2004, and a lower portfolio balance following payment of the special dividend.

For fiscal year 2006, net recognized gains on investments were comprised of net gains on sales of equity investments, net losses on sales of fixed-income investments and other-than-temporary impairments on both equity and fixed-income investments. Net recognized gains decreased in fiscal year 2006 primarily due to increased net losses on sales of fixed-income investments, higher other-than-temporary impairments and fewer net gains on equity investments in the current period as compared to fiscal year 2005. For fiscal year 2006, other-than-temporary impairments were $408 million, as compared to $152 million in fiscal year 2005. The increase in other-than-temporary impairments in fiscal year 2006 was driven by planned sales of certain investments in an unrealized loss position in order to raise funds for the $20 billion tender offer announced on July 20, 2006. Net gains on investments declined $707 million in fiscal year 2005 primarily due to greater sales of investments in the previous fiscal year in preparation for the special dividend paid on December 2, 2004. Net gains on investments also include other-than-temporary impairments of $152 million in fiscal year 2005 compared to $82 million in fiscal year 2004. Net realized gains on sales were $1.65 billion in fiscal year 2004 as we moved to more liquid investment asset classes.

Investments are considered to be impaired when a decline in fair value is judged to be other than temporary. We employ a systematic methodology that considers available evidence in evaluating potential impairment of our investments. If the cost of an investment exceeds its fair value, among other factors, we evaluate general market conditions, the duration and extent to which the fair value is less than cost, and our intent and ability to hold the investment. We also consider specific adverse conditions related to the financial health of and business outlook for the investee, including industry and sector performance, changes in technology, operational and financing cash flow factors, and rating agency actions. Once a decline in fair value is determined to be other than temporary, an impairment charge is recorded and a new cost basis in the investment is established.

We lend certain fixed-income and equity securities to enhance investment income. The loaned securities continue to be carried as investments on our balance sheet.

We use derivative instruments to manage exposures to interest rates, equity prices, and foreign currency markets and to facilitate portfolio diversification. Net losses on derivatives were as follows:

During fiscal year 2006, we experienced lower net losses on derivatives as compared to fiscal year 2005 primarily due to net gains on non-designated equity derivatives in the current fiscal year as compared to net losses in the prior

fiscal year and higher net gains on commodity positions in the current fiscal year driven by increases in the related commodity indices. These gains were partially offset by higher net losses in time value on foreign exchange contracts used to hedge anticipated foreign currency revenues and higher net losses on interest rate derivative contracts.

The net gains on equity derivatives during fiscal year 2006 are primarily due to changes in the market value of non-designated equity derivatives. Gains and losses arising from non-designated derivatives are economically offset by unrealized losses and gains, respectively, in the underlying equity securities which are recorded as a component of other comprehensive income. Commodity derivatives are held for the purpose of portfolio diversification. Net losses related to foreign currency contracts relate primarily to changes in time value of options used to hedge anticipated foreign currency revenues. Additionally, net gains and losses on foreign exchange contracts include the changes in the fair value of derivatives used as economic hedges. These gains and losses are partially offset economically by unrealized losses and gains, respectively, in the underlying assets which are included in other comprehensive income

Net derivative losses in fiscal year 2005 were primarily related to losses on equity derivatives, interest rate derivatives, and foreign currency contracts. During fiscal year 2005, losses related to equity derivatives used to economically hedge against a decline in equity prices were $202 million and losses related to interest rate derivatives were $53 million. These losses were offset by the combination of realized gains on sales of securities and unrealized gains related to increases in the market value of the underlying assets included as a component of other comprehensive income. Net losses related to foreign currency contracts were $53 million, related to changes in time value of options used to hedge anticipated foreign currency revenues and economically hedging foreign currency based investment exposures. Losses related to hedging foreign currency-based investment exposures were offset by unrealized gains in the underlying assets which are included in other comprehensive income. Net losses on derivatives also included gains related to commodity positions used to provide portfolio diversification. Gains on commodity positions were $46 million during fiscal year 2005.

Derivative losses were $268 million in fiscal year 2004 primarily due to net losses in time value on foreign exchange contracts used to hedge anticipated foreign currency revenues.

In the second quarter of fiscal year 2006, we entered into an agreement with NBC Universal, Inc. (“NBC”) that restructured our joint venture relationships for MSNBC Cable L.L.C. (“CJV”) and MSNBC Interactive News, L.L.C. (“IJV”). As a result, we divested 32% of CJV for $331 million and NBC acquired the right, exercisable in the following two years, to buy the remaining 18% interest. In addition, we modified our agreement with NBC to grant to IJV a U.S. content license and to remove the exclusivity obligation on both NBC and Microsoft for local and non-U.S. news content. As part of the MSNBC restructuring agreements, we paid a $200 million fee to effectively terminate IJV’s prior content license agreement and we also prepaid the remaining $14 million license fee to NBC. In the fourth quarter of fiscal year 2006, NBC exercised its option to buy our remaining 18% interest in CJV. For fiscal year 2006, we recognized a net gain of $195 million related to the above transactions.

Income Taxes

Our effective tax rate for fiscal year 2006 was 31% as compared to 26% for fiscal year 2005. During fiscal year 2006, we recorded a tax benefit of $108 million from the resolution of state audits. The increased rate in fiscal year 2006 resulted primarily from the European Commission fine of €281 million ($351 million) which is not tax deductible, and a lower rate in fiscal year 2005 as a result of reversal of $776 million of previously accrued taxes upon settling an Internal Revenue Service examination for fiscal year 1997 – 1999 and a tax benefit of $179 million generated by the decision to repatriate foreign subsidiary earnings under a temporary incentive provided by the American Jobs Creation Act of 2004. Our effective tax rate for fiscal year 2004 was 33%.

Financial Condition

Cash and equivalents and short-term investments totaled $34.16 billion and $37.75 billion as of June 30, 2006, and 2005, respectively. This investment portfolio consists primarily of fixed-income securities, diversified among industries and individual issuers. Our investments are generally liquid and investment grade. The portfolio is invested predominantly in U.S.-dollar-denominated securities, but also includes foreign currency positions in order to diversify financial risk. The portfolio is primarily invested in short-term securities to facilitate rapid deployment for immediate cash needs. Equity and other investments were $9.23 billion and $11.00 billion as of June 30, 2006, and 2005, respectively. As a result of the special dividend paid in the second quarter of fiscal year 2005 and shares repurchased, our retained deficit, including accumulated other comprehensive income, was $18.90 billion at June 30, 2006. Our retained deficit is not expected to impact our future ability to operate or pay dividends given our continuing profitability and strong cash and financial position.

Unearned Revenue

Unearned revenue from volume licensing programs represents customer billings, paid either upfront or annually at the beginning of each billing coverage period, that are accounted for as subscriptions with revenue recognized ratably over the billing coverage period. For certain other licensing arrangements revenue attributable to undelivered elements, including free post-delivery telephone support and the right to receive unspecified upgrades/enhancements of Microsoft Internet Explorer on a when-and-if-available basis, is based on the sales price of those elements when sold separately and is recognized ratably on a straight-line basis over the life cycle of the related product. Other unearned revenue includes services, TV Platform, Microsoft Business Solutions, advertising, and subscriptions for which we have been paid upfront and earn the revenue when we provide the service or software or otherwise meet the revenue recognition criteria.

Unearned revenue as of June 30, 2006, increased $1.74 billion from June 30, 2005, reflecting additions to unearned revenue from multi-year licensing that outpaced recognitions by $1.66 billion, a $53 million decrease in revenue deferred for undelivered elements, and a $127 million increase primarily in unearned revenue for services and subscription services.

The following table outlines the expected recognition of $10.9 billion of unearned revenue as of June 30, 2006:

Cash Flows

Cash flow from operations for fiscal year 2006 decreased 13% to $14.40 billion primarily due to increased payments to fund a $987 million increase in inventory and product costs related to Xbox 360 and increased payments to employees resulting from a 16% growth in headcount. These factors were partially offset by increased cash receipts from customers driven by our 11% revenue growth and $1.74 billion increase in unearned revenue. Cash used in financing was $20.56 billion in fiscal year 2006, a decrease of $20.52 billion from the previous year driven by a $32.57 billion reduction in cash dividend payments. This impact was partially offset by an $11.15 billion increase in common stock repurchases. Net cash from investing was $8.00 billion in fiscal year 2006, a decrease of $7.02 billion from fiscal year 2005 driven primarily by an $8.93 billion decrease in cash from combined purchase, sales, and maturities of investments and a $766 million increase in additions to property and equipment. These factors were partially offset by $3.12 billion of cash proceeds from our securities lending program.

Cash flow from operations for fiscal year 2005 increased 14% to $16.61 billion primarily due to an increase in cash receipts from customers driven by our 8% revenue growth combined with a 12% increase in unearned revenue. Cash payments in fiscal year 2005 resulting from significant legal settlements were approximately $1.8 billion lower than in the previous year, adding to the overall increase in operating cash flow. Partially offsetting these factors were increased payments to employees resulting from a 7% increase in full-time employees. Cash used for financing was $41.08 billion in fiscal year 2005, driven by $36.11 billion of cash dividends paid in fiscal year 2005 compared to $1.73 billion paid in fiscal year 2004. The increase was also partially driven by $8.06 billion in cash used for common stock repurchases, an increase of $4.67 billion in cash used for share repurchases compared to the previous year, reflecting 312 million shares repurchased in fiscal year 2005, an increase of 188.5 million shares compared to the previous year. Net cash from investing was $15.03 billion in fiscal year 2005, an increase of $18.37 billion from fiscal year 2004, primarily due to a $23.59 billion increase in investment maturities that occurred to fund cash dividends paid in fiscal year 2005, partially offset by a $5.32 billion decrease in cash from combined investment purchase and sale activity.

Item 7

Cash flow from operations for fiscal year 2004 decreased $1.17 billion to $14.63 billion. The decrease primarily reflects the combined cash outflows of $2.56 billion related to the Sun Microsystems settlement and the European Commission fine partially offset by increased cash receipts from customers driven by the rise in revenue billings. Cash used for financing was $2.36 billion in fiscal year 2004, a decrease of $2.86 billion from the previous year. The decrease reflects that we did not repurchase common stock in the fourth quarter of fiscal year 2004 combined with a $628 million increase primarily from stock issuances related to employee stock options exercises, partially offset by an $872 million increase in cash dividends paid. We repurchased 123.7 million shares of common stock under our share repurchase program in fiscal year 2004. Cash used for investing was $3.34 billion in fiscal year 2004, a decrease of $3.88 billion from fiscal year 2003.

We have no material long-term debt. Stockholders’ equity at June 30, 2006, was $40.10 billion. We will continue to invest in sales, marketing, product support infrastructure, and existing and advanced areas of technology. Additions to property and equipment will continue, including new facilities and computer systems for research and development, sales and marketing, support, and administrative staff. Commitments for constructing new buildings were $234 million on June 30, 2006. We have operating leases for most U.S. and international sales and support offices and certain equipment under which we incurred rental expense totaling $276 million, $299 million, and $331 million fiscal year 2006, 2005 and 2004, respectively. We have issued residual value guarantees in connection with various operating leases. These guarantees provide that if we do not purchase the leased property from the lessor at the end of the lease term, then we are liable to the lessor for an amount equal to the shortage (if any) between the proceeds from the sale of the property and an agreed value. As of June 30, 2006, the maximum amount of the residual value guarantees was approximately $271 million. We believe that proceeds from the sale of properties under operating leases would exceed the payment obligation and therefore no liability currently exists. We have not engaged in any related party transactions or arrangements with unconsolidated entities or other persons that are reasonably likely to materially affect liquidity or the availability of requirements for capital resources.

In fiscal year 2006, our Board of Directors declared $0.35 per share cash dividends, with $2.69 billion paid as of June 30, 2006. A quarterly dividend of $0.09 per share (or $906 million) was declared by our Board of Directors on June 21, 2006 to be paid to shareholders of record as of August 17, 2006, on September 14, 2006.

On July 20, 2006, we announced the completion of the repurchase program initially approved by our Board of Directors on July 20, 2004 to buy back up to $30 billion in Microsoft common stock. The repurchases were made using our cash resources. During fiscal year 2006, we repurchased 754 million shares, or $19.75 billion, of our common stock under this plan. On July 20, 2006, we also announced that our Board of Directors authorized new share repurchase programs, comprised of a $20 billion tender offer which was completed on August 17, 2006, and an additional $20 billion ongoing share repurchase program with an expiration of June 30, 2011. Under the tender offer, we repurchased approximately 155 million shares of our common stock, or approximately 1.5% of the common shares outstanding, for approximately $3.8 billion at a price per share of $24.75. On August 18, 2006, we announced that the authorization for the ongoing share repurchase program, previously announced on July 20, 2006, had been increased by approximately $16.2 billion. As a result, the company is authorized to repurchase additional shares in an amount up to $36.2 billion through June 30, 2011.

We believe existing cash and short-term investments, together with funds generated from operations should be sufficient to meet operating requirements, quarterly dividends and planned share repurchases. Our philosophy regarding the maintenance of a balance sheet with a large component of cash and short-term investments, and equity and other investments, reflects our views on potential future capital requirements relating to research and development, creation and expansion of sales distribution channels, investments and acquisitions, share dilution management, legal risks, and challenges to our business model. We regularly assess our investment management approach in view of our current and potential future needs.

Off-Balance Sheet Arrangements and Contractual Obligations

Off-Balance Sheet Arrangements

We provide indemnifications of varying scope and amount to certain customers against claims of intellectual property infringement made by third parties arising from the use of our products. We evaluate estimated losses for such indemnifications under SFAS No. 5, Accounting for Contingencies, as interpreted by FASB Interpretation No. (“FIN”) 45, Guarantor’s Accounting and Disclosure Requirements for Guarantees, Including Indirect Guarantees of Indebtedness of Others. We consider factors such as the degree of probability of an unfavorable outcome and the

ability to make a reasonable estimate of the amount of loss. To date, we have not encountered material costs as a result of such obligations and have not accrued any material liabilities related to such indemnifications in our financial statements.

Contractual Obligations

The following table summarizes our outstanding contractual obligations as of June 30, 2006:
