I bought a used computer that has an illegal copy of XP installed on it, and it fails the WGA test, and cannot get any new updates. I have purchased a new copy of XP, but I don't really want to have to reinstall the operating system all over again unless I absolutely have to.
Somewhere on this site was a discussion of how to trick the existing install of XP into re-registering so I can use the new license key, and then become "legal".
I have searched various keywords, but I have been unable to find that original thread. If someone can locate that thread, I would appreciate it.
Edit: I just stumlbed across the Microsoft Product Key Update Tool, but it says it is for use with an electronic license key. Does anyone know if it will work with a retail license? If so, then I think this solves my problem, no?
