Support is ending for some versions of Windows
- Support for Windows Vista without any service packs ended on April 13, 2010.
- Support for Windows XP with Service Pack 2 (SP2) will end on July 13, 2010.*
If you're running one of these versions after support ends, you won't get security updates for Windows.
If you're running Windows XP with Service Pack 2 (SP2) and you're not ready to upgrade to Windows 7, you should install Windows XP Service Pack 3 (SP3), a free update.
Windows XP SP3 includes all previously released updates and a small number of new updates. It won't significantly change the Windows XP experience.
* Note: There's no SP3 for the 64-bit version of Windows XP. If you’re running the 64-bit version of Windows XP with SP2, you have the latest service pack and will continue to be eligible for support and receive updates until April 8, 2014.
