Product divisions

To be more precise in tracking performance of each unit and delegating responsibility, Microsoft reorganized into seven core business groups—each an independent financial entity—in April 2002. Later, on September 20, 2005, Microsoft announced a rationalization of its original seven business groups into the three core divisions that exist today: the Windows Client, MSN and Server and Tool groups were merged into the Microsoft Platform Products and Services Division; the Information Worker and Microsoft Business Solutions groups were merged into the Microsoft Business Division; and the Mobile and Embedded Devices and Home and Entertainment groups were merged into the Microsoft Entertainment and Devices Division.[56][57]

Platform Products and Services Division

The current logo of Microsoft Windows, the company's signature product.

This division produces Microsoft's flagship product, the Windows operating system. It has been produced in many versions, including Windows 3.1, Windows 95, Windows 98, Windows 2000, Windows Me, Windows Server 2003, Windows XP and Windows Vista. Almost all IBM compatible personal computers come with Windows preinstalled. The current desktop version of Windows is Windows Vista. The online service MSN, the cable television station MSNBC and the Microsoft online magazine Slate are all part of this division. (Slate was acquired by The Washington Post on December 21, 2004.) At the end of 1997, Microsoft acquired Hotmail, the most popular webmail service, which it rebranded as "MSN Hotmail". In 1999, Microsoft introduced MSN Messenger, an instant messaging client, to compete with the popular AOL Instant Messenger. Along with Windows Vista, MSN Messenger became Windows Live Messenger.[9]

Microsoft Visual Studio is the company's set of programming tools and compilers. The software product is GUI-oriented and links easily with the Windows APIs, but must be specially configured if used with non-Microsoft libraries. The current version is Visual Studio 2008. The previous version, Visual Studio 2005 was a major improvement over its predecessor, Visual Studio.Net 2003, named after the .NET initiative, a Microsoft marketing initiative covering a number of technologies. Microsoft's definition of .NET continues to evolve. As of 2004, .NET aims to ease the development of Microsoft Windows-based applications that use the Internet, by deploying a new Microsoft communications system, Indigo (now renamed Windows Communication Foundation). This is intended to address some issues previously introduced by Microsoft's DLL design, which made it difficult, even impossible in some situations, to manage, install multiple versions of complex software packages on the same system (see DLL-hell), and provide a more consistent development platform for all Windows applications (see Common Language Infrastructure). In addition, the Company established a set of certification programs to recognize individuals who have expertise in its software and solutions. Similar to offerings from Cisco, Sun Microsystems, Novell, IBM, and Oracle Corporation, these tests are designed to identify a minimal set of proficiencies in a specific role; this includes developers ("Microsoft Certified Solution Developer"), system/network analysts ("Microsoft Certified Systems Engineer"), trainers ("Microsoft Certified Trainers") and administrators ("Microsoft Certified Systems Administrator" and "Microsoft Certified Database Administrator").[9]

Microsoft offers a suite of server software, entitled Windows Server System. Windows Server 2003, an operating system for network servers, is the core of the Windows Server System line. Another server product, Systems Management Server, is a collection of tools providing remote-control abilities, patch management, software distribution and a hardware/software inventory. Other server products include:

Microsoft SQL Server, a relational database management system;

Microsoft Exchange Server, for certain business-oriented e-mail and scheduling features;

Small Business Server, for messaging and other small business-oriented features; and

Microsoft BizTalk Server, for business process management.[9]
