Easiest way to hack a Windows admin password

Say your pc becomes disconnected from your network and there by your domain where your user accounts are controlled or someone dies it may be necessary to hack a windows Administrator password.

While the Offline NT Password & Registry Editor, Bootdisk / CD seemed like easiest method for resetting windows passwords I had trouble with it and had to find an alternate method.

This alternate method consisted of booting up the machine with Linux distro Knoppix, and copying the system32/config directory which contains the SAM file onto a usb flash drive. The SAM file is the Security Accounts Manager Windows uses to store password "hashes" which amounts to essentially encrypted passwords.

I then copied the necessary files to another windows machine on which I had installed SAMinside. SAMinside was instantly able to tell me all the user names for the locked box and offered the ability to do a brute force / dictionary hybrid attack that tried over 4 million passwords a second. Luckily, the password i was trying to crack was a simple 6 letter dictionary word so it only took about an hour.
