If you are getting the following error message when attempting to update to SP1:

Error Message: 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)
