Just a quick post as i cant seems to find what i need via Google. Im formatting my Girlfriends parents PC in about an hour but i have ran into a slight problem. They have lost the original XP CD with the license key. Now XP is already installed and i need a way to find out/request the Current CD key in use on the System. I have an ISO of XP ready to use but i would like to use the original legit key that came with the system if possible as its not powerful enough to be upgraded to Vista or Seven. So any help appreciated.
