Windows stores its user information, including crypted versions of the passwords, in a file called 'sam', usually found in \windows\system32\config. This file is a part of the registry, in a binary format previously undocumented, and not easily accessible. But thanks to a German(?) named B.D, I've now made a program that understands the registry. This site provides CD and floppy images for end users to easily edit their forgotten passwords.

Trinity Rescue Kit or TRK is a free live Linux distribution that aims specifically at recovery and repair operations on Windows machines, but is equally usable for Linux recovery issues.

crowbarDMG is a dictionary attack tool for DMG and Spareimage files for Macs. It does require 10.5 Leopard. It really wasn’t worth the trouble to redo things to work on Tiger. It is completely free, so enjoy. Be sure to read the included PDF readme file. I address an issue if you use strings to pull out a dictionary from a disc image. Some control characters need to be scrubbed else it will crash crowbarDMG. Give it a shot if you need to recover a password for a dmg or filevault file.
L0phtCrack is a password auditing and recovery application (now called L0phtCrack 6) originally produced by Mudge from L0pht Heavy Industries. It is used to test password strength and sometimes to recover lost Microsoft Windows passwords, by using dictionary, brute-force, hybrid attacks, and rainbow tables. It was one of the crackers' tools of choice, although most use old versions because of its low price and high availability.
