Need to chnage license key RRS feed

  • Question

  • I recently did a windows repair on my home system, and used the wrong windows CD/license key (it's an expired/invalidated volume licensed edition from a company I used to work for).  I have since found the correct CD/key.  How can I change the license key back to the original?  Do I need to run repair again?  or is their a simpler way.

    P.S. I have not included the MGAdiag output here because the machine is still having serious issues and I cannot get the diag to run.  I desperately do not wish to have to reinstall the OS, as I have tons of third party hardware and software installed on this machine.

    Thanks in advance.

    Thank you for contacting the Windows Genuine Advantage (WGA) program forum.

    If you have a Microsoft Certificate of Authenticity (COA) for Windows XP affixed to your system, then there is a strong likelihood your system is licensed to run Windows XP.
