Desktop and Enterprise Software and Services 

Desktop and Enterprise Software and Services revenue was $17.84 billion, $20.40 billion, and $22.41 billion in 1999, 2000, and 2001. Desktop and Enterprise Software and Services includes Desktop Applications; Desktop Platforms; and Enterprise Software and Services. 

Desktop Applications revenue was $7.77 billion, $9.30 billion, and $9.54 billion in 1999, 2000, and 2001. Desktop Applications includes revenue from Microsoft Office; Microsoft Project; Visio; client access licenses (CALs) for Windows NT Server and Windows 2000 Server, Exchange, and BackOffice; Microsoft Great Plains; and bCentral. In fiscal 2001, revenue from client access licenses increased 14% reflecting strong licensing growth of Windows NT Server and Windows 2000 Server CALs. Office revenue growth was flat during the year. In fiscal 2000 and 1999, revenue growth from Microsoft Office integrated suites, including the Premium, Professional, Small Business, and Standard Editions were very solid. 

Desktop Platforms revenue was $6.74 billion, $7.02 billion, and $8.04 billion in 1999, 2000, and 2001. Desktop Platforms includes revenue from Windows 2000 Professional, Windows NT Workstation, Windows Me, Windows 98, and other desktop operating systems. Fiscal 2001 revenue growth reflected the strong adoption of Windows 2000 Professional, partially offset by flat revenue growth from Windows Me and Windows 98 operating systems, reflecting the slowdown in consumer PC shipments and a higher mix of Windows 2000 Professional and Windows NT Workstation. In fiscal 2000, Desktop Platforms revenue growth was modest due to soft demand for business PCs during most of the year; a slowdown in shipments in anticipation of the post mid-year availability of Windows 2000 operating systems; and, as expected, a longer business migration cycle for the newest Windows operating system offerings. In fiscal 1999, Windows units licensed through the OEM channel, particularly Windows NT Workstation, increased strongly over the prior year. Organizational licensing of Windows NT Workstation and Windows 98 also contributed to the growth. 

Enterprise Software and Services revenue was $3.33 billion, $4.08 billion, and $4.83 billion in 1999, 2000, and 2001. Enterprise Software and Services includes Enterprise Platforms, Server Applications, Developer Tools and Services, and Enterprise Services. As a result of the continued adoption of Microsoft’s .NET Enterprise Server offerings in fiscal 2001, Server Applications revenue increased 31% versus the prior year. Enterprise Services revenue, representing consulting and product support services, was up 34% compared to fiscal 2000. Enterprise Platforms, which includes Windows 2000 Server and Windows NT Server operating systems, increased 10% while revenue from Developer Tools and Services was flat with the prior year. In fiscal 2000, Enterprise Platforms revenue growth was particularly strong led by increased adoption by customers of Windows NT Server and Windows 2000 Server. Revenue from Server Applications grew strongly, largely due to the strong success of SQL Server 7.0. Software
