Windows 7 recovery tool - Unlock My Password
Unlock My Password is designed to reset passwords on any Windows platform. It works on Windows NT, 2000, XP, Vista, and both versions of Windows 7 (32-bit and 64-bit). It is completely safe, and does not cause harm to any component or registry file. It does not tamper with any other security protocol nor change any of the settings of your computer system. Once the login information is reset, you can easily change it back to an original password, or any other password you desire.
