Offline NT Password & Registry Editor is for advanced users who want to reset the password of any user that has a local account on your Windows system.
For some background, Windows stores your user information, including encrypted versions of the passwords, in a file called 'sam,' usually found in windowssystem32config. This file is part of the registry, in a binary format and not easy to get at.
Offline NT Password & Registry Editor is designed to get around this and make it simple to access that part of the registry.
Offline NT Password & Registry Editor can detect and offer to unlock locked or disabled out user accounts without knowing the password.
There is also a registry editor and other registry utilities that work under Linux and Unix should you have other things you need to modify in the registry.
Advanced users should only use Offline NT Password and Registry Editor. There are a lot of things that could go wrong here. Documentation is available at the homepage.
This zip file contains both the USB and DVD files required.
