Forget your Windows Admin Password?
Never fear… Don’t re-install Windows. Boot from a floppy or CD and use the Offline NT Password and Registry Editor which can be found at http://home.eunet.no/~pnordahl/ntpasswd/.
After you boot it’s pretty simple to reset the Administrator password.
1. Select the partition that contains your Windows install.
2. Specify the path to the registry files, e.g. WINNT/system32/config/
3. Select 1 to load SAM, SECURITY and SYSTEM files
4. Select 1 to edit user data and passwords.
5. Specify the user you wish to alter. Administrator is the default, but you can specify any user you wish.
