  • Keep in mind that most OEM XP and up license key stickers were special numbers to begin with. You can't usually reinstall with that number, and I believe the number in the registry reflects the number on the case. Aug 30, 2009 at 15:06

    Note that Fortyrunner has said that the registry is on ANOTHER disk from another computer. Using Jellybean/WinKeyFinder/KeyFinder as suggested will not work in this instance.

  • and why would winkeyfinder not work? connect the HDD to any computer (to be sure, remove all other HDDs), now boot from a windows XP CDROM and run a repair installation, then retrieve your license keys with winkeyfinder. walk in the park.
