I know somone who has Windows XP Pro 32 bit installed on his PC. He lost the CD. Windows XP Pro really needs to have at least a Repair Install or a "Clean Install" (Recommended). I have exactly the same version of the Windows XP Pro CD (different Product Key) that he has installed on his PC. Is it possible to do a Repair Install on his PC using my Windows XP Pro CD? Is it possible to do a "Clean Install" on his PC using my Windows XP Pro CD and his Product Key? Thanks in Advance.
