  • As with many of these applications, you should avoid using your machine while LCP recovers passwords, as it will consume the majority of your machine resources for the crack.

  • Ophcrack  is one of the most popular password recovery tools. It's free (open source as well), cross platform, and very reliable. Ophcrack uses a solid implementation of rainbow tables that just happens to have been done by those who created the method.

  • Ophcrack runs on Windows, Linux/UNIX, and Mac. It cracks LM and NTLM hashes; has free tables for XP, Vista, and 7; includes a brute-force module for simple passwords; offers an audit mode and a CSV export; presents real-time graphs; has a LiveCD for easier (and more efficient) recovery; and dumps and loads hashes from encrypted SAM.
