my friend is trying to install xp pro, he is replacing a pre installed version of the same, what is happening is that after formatting xp wont recognise the product key on the new xp pro,i know this is correct,it seems to be saving the key from the version before formatting. even after formatting it still remembers the old key and wont accept a new one for the new version , is xp creating a hd partition to save the old key to ??? we cant find out how you check whats on each partition either.......... what i need is to be able to totally erase all trace of the old key no; and re install my new version and new key.....how can it remember old key no after formatting
thankies for help
