Put your Windows XP caps on, Windows XP isn’t dying until 2011. It was supposed to be dead on July 31st, 2009! The availability to downgrade to Windows XP for businesses goes as far as April 23rd, 2011. The reason for this delay is that this will get companies to make an easier switch to Windows 7.  So what that means is that Windows XP will be available 18 months after the release of Windows 7 or the first service pack (SP1). Basically, which ever is sooner.
