Windows XP - Change a Windows XP Product Key
NOTE: Windows 95/98, Windows Me, Windows 2000, Windows XP, and Windows Vista are no longer supported by the Help Desk. We can only provide best effort support. If we are unable to resolve your Windows 9x/2000/XP/Vista issue, you may be able to find help in Microsoft's Knowledge Base.
These products are no longer actively supported by Microsoft. No further development will take place on these products and security updates are no longer issued. It is highly recommended that you upgrade to Windows 10, 8, or 7.
If you want to change the product key because of Microsoft's key block beginning in June, 2007, you should first:
- Verify that the user is eligible to use software under the UWS/WTCS Windows XP license, which essentially means that they are currently employed faculty or staff.
- Verify that the computer is owned by the school and that it is in use in the blocked area (outside the US).
- Verify that the computer’s key is the one Microsoft is blocking: http://kb.wisc.edu/helpdesk/page.php?id=5766. The blocked key begins with CTQBH and ends with 2DRDT.
To change the key (you do need administrative rights to complete this procedure), follow the Use the Activation Wizard directions found on this page: http://support.microsoft.com/kb/328874. You can ignore step 13 (Install Windows XP SP1 or a later version of Windows XP).
