chntpw - 140201-1 main

This little program provides a way to view information and
change user passwords in a Windows NT/2000 user database file.
Old passwords need not be known since they are overwritten.
In addition it also contains a simple registry editor
(same size data writes) and an hex-editor which enables you to
fiddle around with bits and bytes in the file as you wish.
.
If you want GNU/Linux bootdisks for offline password recovery
you can add this utility to custom image disks or use those provided
at the tools homepage.
