In this tutorial we’ll show you how to crack and reset Windows password when you forget it or want to unlock a computer with an unknown password. There are tons of recovery tools available to bypass password, but here I’ll use the freeware Ultimate Boot CD (UBCD).

Ultimate Boot CD is a Linux-based bootable disc with loads of useful software for repairing or fixing almost any Windows problem. The built-in chntpw utility could be used to wipe windows passwords and view/edit the registry. Here’s how.

Note: Ultimate Boot CD is a freeware so don’t expect it to work with domain controllers. If you want to find a more powerful yet easy-to-use password recovery software, try the PCUnlocker Live CD.
