regarding some of the previous comments about ophcrack vista 3.6.0 not loading tables, I have same problem, and have a solution. Problem: Boot ophcrack vista 3.6.0 live from CD, then see: "Tables found: /media/sr0/tables/vista_proba_free/table0.bin" then see: "Did not find the requested table(s) ... [same as above]" What happens is that the auto configure program "ophcrack-launcher.sh" that is run automatically or manually, found the table, but passed the full table path to ophcrack, instead of just the directory that the table is in. Here is the solution: Edit that file to fix (you need to know vi, I can't help you on that): vi /usr/bin/ophcrack-launcher.sh Find line at almost the end "Starting ophcrack", and in the next line change -t $table_inline to -t $(dirname $table_inline) then try ophcrack-launcher.sh again. This change will be lost at every reboot. If you can't edit that file, you can always run ophcrack by hand from command line: ophcrack -d / \ -t /media/sr0/tables/vista_proba_free \ -w /media/sda2/Windows/System32/config \ -n 9 \ -o /tmp/ophcrack.txt \ -g The 9 is one plus the number of CPU cores in your system. The sda2 is where the windows hard drive shows on your system. Both will likely need to be changed to suit your setup. Works fine after this. John Refling
Every time I forgot a Windows password, I will try Ophcrack firstly to recover the password. When the tool can't find the password, I then use PCUnlocker Live CD to bypass the password.

Yeah! I agree with you. Ophcrack is a great free reset tool. But sometimes it can't guarantee my data's security. So for the security of your data, you can use another tool named Windows Password Killer. More details you can download Windows Password Killer in Google. Hope it can help you. Good luck!
