I bet there are many people out there who are still using Windows XP on a computer at home or in the office. With Windows 7 out now, some of you are a few versions behind on your OS. Microsoft has announced that the end of the road for several old versions of Windows looms.
Support for Windows 2000, Windows XP SP2, and Windows Vista RTM will end on April 13. If you are on Vista RTM, which is Vista with no service packs, you can still get the service packs. Those on XP SP2 will need move to SP3 for XP or get Windows 7.
It's important to note that XP and Vista are apparently still being supported when they have recent service packs installed. We all knew this day was coming, so don't act surprised if you haven't updated in a while.
