samunlock - unlock users in the SAM user database
Contents
Description
This manual page documents briefly the samunlock command.
samunlock is a non-interactive command line utility that can unlock a user and/or the user's account bits
from the SAM user database file of a Microsoft Windows system (Windows NT, 2000, XP, Vista, 7, 8.1,
etc.). This file is usually located at \WINDOWS\system32\config\SAM on the file system of a Microsoft
Windows Operating System
On success, the program does not output any informatin and the exit code is 0.
Examples
samunlock-U-utheboss
Unlock an user named 'theboss', if found.
samunlock-U-u0x3ea
Unlock an user with RID '0x3a'.
Known Bugs
If the username includes international (non-ASCII) characters the program will not (usually) find it. Use
the RID number instead.
