I have just recently purchased a used laptop which came with an original XP professional disc. (which includes service pack 2). How can i find out if the XP Pro CD that i have is the same/registered copy installed on my machine? I woud like to re-format my laptop with this CD but dont want to do that unless i know for ceratin the CD i have is registered to my laptop/MAC address.
Also, is their a microsoft home webpage that i cant visit and check if the XP Pro CD i have is registered/licensed to a machine?
