When Windows XP is originally installed, a key must be entered. How do you change this key once XP has already been installed? Of course I am refering to the key generator that is discussed at length in another thread. Assume the FCKGW.... key was used for the original install. How do you change it to a randomly generated key from the key generator? I am curious about this because what good is the key generator (that has recently stirred up so much interest) if the keys it generates cannot be used unless you are doing a clean unstall?
