I have just done two installs of XP Pro side by side, but have then mixed up the Product Key labels which means I now don't know which label belongs to which PC. Is there a way of establishing which label is for which PC without having to reinstall?

U Can use XP Key test to work it out, it won't take too long to do, just a little patience... I'm not sure if it's still available, but u used to be able to get it from: *********
