to enter a 25 digit Windows XP Product Activation Key Code, which Windows XP promptly converts it into the system's product ID. Because of security concerns about piracy, Microsoft does not provide a tool that allows you to view the Product Activation Key (or CD Key) that was used to install the operating system. However, 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 The following message will be displayed if installation fails for this reason: Service Pack 1 Setup Error: The product key used to install Windows is invalid. Please contact your system administrator or retailer immediately to obtain a valid product key.

Please be assured that any personal information you send to the Microsoft Anti-Piracy team will be kept in strict confidence.
