I'm running XP Pro Corp, and have been reading up on the new details and whatnot. I originally installed the XP Pro edition final before it was released on my new Dell Computer (which had WinMe installed with a voucher for XP Pro when it was released).......anyway........with SP1 deactivating the Corp key I most likely have....my question is this. Since I do actually HAVE a legal copy and serial, is there a way to change my CD key to the legal one I have so I don't get locked out of updates? Will I have to totally reinstall the OS, or is there an easier way to change my CD key through the registry or somethin'? Thanks!!!!!
