Total Windows Password Reset is a password recovery tool. It supposedly can reset any password, be it an Administrator or regular user account so that you don't have to type it any more. This is obviously useful when you don't remember the password.
The application does its magic under the hood. Since it can't get the passwords while Windows is running, it has you boot up a version of FreeDOS with a batch file that performs a couple of operations. To let you boot up your system to that batch file, the application offers two methods: DVD or USB. Total Windows Password Reset comes with an ISO file that you can burn to a CD or DVD to boot your system. You can also format a USB drive and copy some files that are also included to boot up your system that way.
In my testing, the application booted up quite fine, but it returned some errors and quit. It didn't even restart Windows, it left a DOS command line opened, which made me feel like I traveled in time to 1995. So, the application didn't work for me, but it might do for you. The trial version allows you to test it without paying.
