Offline NT Password & Registry Editor (v060213 - February 2006)
Petter Nordahl-Hagen has written a Windows NT/2000/XP offline password editor:
http://home.eunet.no/~pnordahl/ntpasswd
Works with syskey (no need to turn it off, but you can if you have lost the key)
Will detect and offer to unlock locked or disabled out user accounts!
Caution: If used on users that have EFS encrypted files, and the system is XP or later service packs on W2K, all encrypted files for that user will be UNREADABLE! and cannot be recovered unless you remember the old password again!

To write these images to a floppy disk you'll need RawWrite2 which is included in the Bootdisk image download. To create the CD you just need to use your favorite CD burning program and burn the .ISO file to CD.
