WinPassword (formerly known as NT Password) is an application for NT / 2000 / XP / 2003 / Vista / 2008 / Windows 7 system administrators for finding breaches in system security. It tries to recover plain-text passwords by analyzing user password hashes. If it is possible to recover a password within reasonable time, the password should be considered insecure. Windows Password can also be used to recover lost passwords of particular users. Please note that this program is for advanced users and system administrators with good understanding of the NT security model.
