On to the next program. This is my favorite one, because it's around 3MB for the entire image, and instead of going through a crack process, it completely blanks the windows password in very little time. It's called “Offline NT Password & Registry Editor”, and can be downloaded here. http://home.eunet.no/pnordahl/ntpasswd/cd070927.zip

Just download the image, unzip it, and burn to cd. Cd's are cheap, so don't complain about wasting a cd for 3MB of space.

Once you boot to it, it will try and autodetect everything. Unless you install Windows in funky directories, all defaults will do the trick. The menu is very straightforward and easy to use.

I selected the admin account (the more difficult password) which is the default. Then I used the command * to blank the password. Then I typed in the name of the other account, and blanked it as well. This took around 3 minutes total including boot time. Then I exited, making sure to save my changes. Once I rebooted into windows, I logged into my accounts with NO password. Everything worked perfectly and I had admin privilges.
