The cd key is stored as clear text in Windows 9x and Windows NT4, but newer versions of Windows and Office encrypts the cd keys a little.
To help decrypting the cd keys, then one can use the following utilities:
- Magical Jelly Bean Keyfinder (Can also change the cd-key for Win9x,WinXP and Win2k3)
- ProduKey (Can also retrieve the product key from another computer)
- Windows Product Key Viewer
- RockXP (Win2k/XP only, can change the XP key)
- Bob’s XP-Keyview (XP only)
- ViewKeyXP (XP only, doesn’t support SP2)
