It has finally come. The day that so many have been trying to ward off using good vibes and a lucky rabbit-foot. Windows XP Service Pack 2 is at end of life. No more security updates after this Tuesdays release - so if you run Windows XP SP2 - Patch up now.Of course you could install Service Pack 3 and get a little longer out of that PC - Windows XP SP3 will be supported by Microsoft until at least April 2014.
The service pack, which was first released in August 2004, will no longer be supported by Microsoft after Tuesday meaning that users will no longer receive any security patches - regardless of how critical any discovered vulnerability may be.
Furthermore, it's not just Windows XP SP2 that Microsoft won't be updating - but your installations for Internet Explorer, Windows Media Player, Outlook Express and other Windows XP SP2 components also won't receive security patches if you're running that version of the operating system.
