This little program will enable you to view some information and change user passwords in a Windows NT SAM userdatabase file (NT/2k/XP/Vista etc system). You do not need to know the old passwords. However, you need to get at the file some way or another yourself. In addition it contains a simple registry editor with full write support, and a hex-editor which enables you to fiddle around with bits&bytes in the file as you wish.
