If you see the following message while visiting Windows Update:

Error Message: The Product Key Used to Install Windows Is Invalid
http://support.microsoft.com/default...&Product=winxp

You'll have to purchase a new, legitimate, "Full Version" of Windows XP Professional
and perform a "repair install".
