Lost your user account password in Windows? It only seems to happen when you have a ton of work to do and you've procrastinated until the last minute. Lost your administrator password? You'll need that password to access diagnostic tools to fix major system problems. It's really frustrating trying to guess a password you've probably never used while troubleshooting a dying computer.
Do not fear! Ophcrack is here! Ophcrack is a free (yes, you read that correctly) program that can recover just about any lost password. The LiveCD version of Ophcrack fits on a CD and does a very good job at "cracking" or "hacking" your lost password.
I've put together a step-by-step guide to using Ophcrack LiveCD to recover your password, complete with screenshots and help burning the CD, booting to the CD, etc. Using this guide, you should be able to hack your own password with Ophcrack LiveCD even if you've never tried anything like this before. It's that easy.
I also have a full review of Ophcrack that discusses some of the important features of the program.
Edit (July 31, 2010) : If you're having problems using Ophcrack, try the following:
- Read the "step by step guide" linked above if you haven't already.
- Read the comments below.
- Leave a comment below or in my forum asking for help.
- Try Offline NT Password & Registry Editor, PC Login Now, or Kon-Boot, three other programs that work completely differently and so might work if Ophcrack doesn't agree with your PC.
- ... or if you're hell-bent to get Ophcrack to work, try asking for help on the official Ophcrack forums.
