Windows Lifecycle Policy

Microsoft has stopped releasing updates and hotfixes for many old Windows operating systems, including all versions of Windows 9x and earlier versions of Windows NT. Windows versions prior to XP are no longer supported, with the exception of Windows 2000, which is currently in the Extended Support Period, that will end on July 13, 2010. Windows XP versions prior to SP2 are no longer supported either. Also, support for Windows XP 64-bit Edition ended after the release of the more recent Windows XP Professional x64 Edition.^{[citation needed]} No new updates are created for unsupported versions of Windows.
