i have windows xp pro sp1a installed and i wish to change the cd key. i've checked out the web and the solution that is widely suggested is to change a registry value to deactivate windows and then run the windows activation wizard. But when i do this it just says that windows is already activated. Which is wierd because i never activated windows. But the other solution i tried involves a program called Windows xp product key modifier but it uses the same method of altering the registry which doesn't work for me. Any ideas anyone?
