Microsoft is now offering buyers of Windows XP Home Edition and Windows XP Media Center Edition an added 5yr customer support for both operating systems. The extension should give home users a good two years to upgrade to Windows Vista-or even ditch Windows altogether and go with Linux or a Mac-before Microsoft stops supporting XP Home or XP MCE. This isn't the first time Microsoft has extended support for a consumer OS. Three years ago, the company extended the support period for its Windows 9x operating systems, including Windows 98 and Windows ME, until June 30, 2006.
