Windows XP
 

Yeah, so M$ just confirmed that Windows XP is going to be unsupported by M$ on April 14, 2009(5 days). This means there will be no security/exploits fixed, and no support from their site. I encourage all of you to upgrade from XP to Windows 7(use the UPGRADE option, you can keep all files, and settings).

If you don't have a copy of Windows 7 Beta you can download the latest build of RC from Demonoid. Build 7106 is the latest build to this date. Also, even if XP was still supported Windows 7 surpassed XP in shutdown, bootup time and almost every other test.

Windows 7 will most definitely be M$' best OS yet!
