Resetting Administrator Passwords

To reset, use a boot floppy or CD (or flash drive?) created from this site.

NOTE: If used on users that have EFS encrypted files, and the system is XP, all encrypted files for that user will be UNREADABLE! and cannot be recovered unless you remember the old password again

From the site:

I've put together a single floppy or CD which contains things needed to edit the passwords on most systems.

The bootdisk supports standard (dual)IDE controllers (built in), a lot of SATA-controllers, and most SCSI-controllers with the drivers supplied in a seperate archive below. PS/2 keyboard or USB-keyboard supported (mouse not required) It does not need any other special hardware, it will run on 486 or higher, with at least 32MB (I think) ram or more. Unsupported hardware: MCA, EISA, i2o may not work.

Tested on: NT 3.51, NT 4 (all versions and SP), Windows 2000 (all versions), Windows XP (all versions, also SP2), Windows Server 2003 (at least Enterprise).


Microsoft also has a knowledge base entry that addresses resetting XP passwords:
How to log on to Windows XP if you forget your password or your password expires
