- Cracks LM and NTLM Windows hashes
- Free tables available for Windows XP, Vista and 7
- Brute-force module for simple passwords
- Audit mode and CSV export
- Real-time graphs to analyze the passwords
- LiveCD available to simplify the cracking

I created 3 different bootable USB sticks - using "tazusb.exe" - 4GB, 8GB and 16GB. I also added it to my YUMI USB stick which has lots of .ISOs on it that all work. None of them booted ophcrack. Two of them just displayed one line... something about Linux and a name like "Aaron", and one of them just showed a blinking cursor at the top of a blank screen. I tried all of them on a Netbook and my new Desktop. Total failure. I also burnt a CD. It didn't boot either. Fortunately, I read someone else's comment about "Hiren's Boot CD" (thank you, "dahoppsrno1"!). That has a utility on it to clear passwords and it works.
This software rocks!!! It's just recovered my lost login password with hardly any effort and no fuss. For the past year I've been using a fingerprint reader to logon to my laptop. After many "too slow" or "Too fast" comments while trying to use the device, I decided to uninstall it. On rebooting I was met with the password screen, but what was the password???? After much shouting and hair pulling, a friend told me about Ophcrack. So I downloaded the iso file, burnt it to CD and inserted into the drive of my password protected laptop. A few minutes later i'm looking at my lost password. Yesssss. Nuff said It works.
I just purchased the password kit and after starting from the CD it says it did not find an operating system on my hard drive. Now what do I do? Oh course this was not one of the FAQ. Can anyone help me. Thanks
I use Spotmau to crack admin passwords on machines I repair. Not even Hirens is as comfortable to use.
