While I think it's less common these days, many people still use product key generators or other illegal tools to get product keys that work to install Windows only to find out later, when they try to activate Windows, that their original plan isn't going to work out. You can change the product key manually by making certain registry changes or by using a wizard available in Control Panel. Since some versions of Windows use slightly different names for some menus and windows, pay close attention to the differences that are called out in those steps.Note: The steps involved in changing your product key differ considerably depending on which Windows operating system you're using. It's important to take great care in making only the changes described below!
I have a Windows XP Pro SP2 installation disk but I don't know the CD Key. I do not have this installed on any other computers so I can't search the registry for it either.But beginning with Windows XP, PC makers were able to dramatically change the Windows install disc, so much so that, in some cases, those discs weren't even identifiable as valid install media to Windows Setup. In Windows Vista, Microsoft supported in-place upgrades from Windows XP, but if you wanted to use an Upgrade version of the Windows Vista Setup disc to do a clean install, you had to perform a weird double install trick.(I documented this process in How to Clean Install Windows Vista with Upgrade Media.) When it comes to performing a clean install of Windows 7 using Upgrade media, there's no simple answer.It's an excellent alternative solution to changing the Windows XP product key code manually.
