Ophcrack  uses Rainbow Tables to crack NTLM and LM hashes into plain text, its a free Windows password cracker based on rainbow tables. It is a very efficient implementation of rainbow tables done by the inventors of the method. If you have a complex password it will take a lot longer than simple passwords.
