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.
Hey kaywat716, download Hirens ISO. It has pwd reset tools for any account. Interesting tool, but even using the largest table, unable to crack my Upper and lower case alpha-numeric with special character password. I imagine testing the security etc of passwords can be useful, yet resetting takes minutes.
