On 13 June 2010, support for Windows XP Service Pack 2 and Windows Vista (without Service Pack) is ending. This is what Microsoft has announced in today’s German issue of the Microsoft Windows newsletter.
To continue receiving security updates, it is recommended to upgrade to either Windows 7, or temporarily to Windows XP Service Pack 3 or Windows Vista Service Pack 2. With these service packs, your support will be maintained until April 2014.
You can find more information about this on the overview for ending support.
