March 21, 2008 (Computerworld) The approaching death of Windows XP may upset you, but it shouldn't come as a surprise. Microsoft Corp.'s product life-cycle guidelines have foretold the fate of XP since 2001. In fact, Microsoft has been killing off one version of a product as it is replaced with another for years now. But this time around, the approaching demise of XP is getting more attention than, say, the final passing of Windows 2000.

This incipient consumer rebellion is a relatively new phenomenon, even in the short history of PCs. For most of the '90s, Microsoft couldn't bring out new products fast enough to satisfy customers. Computing technology was exploding, and Windows exploded along with it, from Windows 3.1 to Windows 95 to Windows 98 to Windows 98 Second Edition to Windows Millennium Edition. PC sales boomed and Windows users raced to upgrade to the latest version.
