Microsoft to End Support for Windows XP SP2 and Windows Server 2000 and Client (December 7, 2009) Users running older versions of Windows have seven months to upgrade to newer versions before Microsoft cuts off support.

As of July 13, 2010, Microsoft will no longer support windows XP SP2, Windows 2000 Server and Windows 2000 Client. Users of those operating systems are urged to upgrade to Windows 7, Windows Server 2003 or Windows Server 2008.

Microsoft is offering online resources to ease the transition, including a Windows XP to Windows 7 migration guide and a Windows 7 Automated Installation Kit. Microsoft will probably continue to issue important security updates for XP and 2000 after the official support period ends, but will no longer issue service packs or other non-critical updates.
