Error Message: The Product Key Used to Install Windows Is Invalid

Checking the Product ID
Windows XP Service Pack 1 ships with a list of the two product IDs that are
created by the pirated product volume license product keys.

(The Product ID can be found by right clicking My Computer and choosing
Properties) To determine eligibility for the update, Service Pack 1 compares
the Windows XP product ID on the system to this list.

The comparison and the list reside locally on the users PC and no
information is sent to Microsoft as part of this process. Service Pack 1 for
Windows XP will fail to install on installations of Windows with one of the
following product IDs: XXXXX-640-0000356-23XXX and XXXXX-640-2001765-23XXX
