It appears you have a pirated, illegal version of Windows XP Professional
installed on that computer.
Run the Windows XP Product Key Validation Assistant:
http://www.microsoft.com/resources/h...s/default.mspx
You receive a "The product key used to install Windows is invalid" error message:
http://support.microsoft.com/default...&Product=winxp
If you are getting the following error message when attempting to update:
"The product key used to install Windows is invalid"
You'll have to purchase a new "Full Version" of Windows XP Professional
and perform a "Repair Install" using the new Windows XP Pro CD and Product Key
that comes with it. (You cannot simply change the Product Key)
