From http://ophcrack.sourceforge.net/:

Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman’s original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds. It is a very efficient implementation of rainbow tables done by the inventors of the method. It comes with a GTK+ Graphical User Interface and runs on Windows, Mac OS X (Intel CPU) as well as on Linux.

The Ophcrack LiveCD (462MB ISO file) contains a full Linux system (SLAX), Ophcrack for Linux and rainbow tables for alphanumerical passwords. The LiveCD cracks passwords automatically; no installation necessary; no admin password necessary (as long as you can boot from a CD).

On BSNL’s broadband-on-steroids, the 462MB was on my hard disk in 36-minutes flat! Now that’s a great home-coming gift from BSNL.

Note:

January 31st marked the end of my academics at SP Jain Institute of Management & Research. The next phase is a two-month internship that began yesterday – the 5th of February. In between the 31st and yesterday, I was savouring the sights and smells of good old Bangalore; that’s why you didn’t read a word on this blog. But I MISS Mumbai – terribly! In January last, everyone said, “Look, whatever you might say about Mumbai today, a year down the line you’ll be singing the exact opposite.” And that is exactly what has happened. In my opinion, it’s Mumbai that SHOULD be coined as “The City of Love.”

That, however, is a topic for an emotional post one of these days. Watch out!

I have downloaded windows password key 8.0. It is a very quick and useful utility for resetting passwords. It not only supports XP, 2000, and NT, I have personally tested it with Vista Home Premium and Ultimate. It works perfectly to reset any local user account to a blank password.
Just an easy to use bootable CD/DVD . It can also be used on a USB Flash Drive. http://www.lostwindowspassword.com/
