Find below a nice utility to :
- To reset the password of any user that has a valid (local) account on your Windows NT/2k/XP/Vista/Win7 etc system.
- You do not need to know the old password to set a new one.
- It works offline, that is, you have to shutdown your computer and boot off a floppy disk or CD or another system.
- Will detect and offer to unlock locked or disabled out user accounts!
- There is also a registry editor and other registry utilities that works under linux/unix, and can be used for other things than password editing.
You can get it from here.
