For educational purposes only! These set of instructions on instructables.com tell of a way to crack windows passwords. You know, the log in password of your neighbor- no I mean the password that you, um, lost the other day… Basically, it uses a Linux distro (Slax, I believe) with its special software. The software is called Ophcrack, which is part of this Linux distro. The cd itself is a live cd which means you boot up with it. After boot, the applications in this cd automatically scans your computer for passwords of log in accounts (SAM Files) and then displays them for you. This means that you do not have to reset any passwords. You can actually view the old password that you… lost… This should be very helpful whenever you loose your password because we just happen to loose our windows account log in passwords all the time
