Okay , heres the Score, this is not some serial request. My brother has lost his CD key for XP. he has XP Home edition. I know I have seen, when this used to be called windows Xperience, a post that said how can get your key from somewhre of the system. He has a bonifide copy of XP so he obviously wants a bonifide product key so he can have his service packs etc. Any Ideas.
