    I got the LIVE disc and burned it to CDR. After one try with "automated," on Windows XP Professional, I clicked on the link to reveal the password. It said, "file not found." Fortunately, the program did show that the Administrator account had no password set at all, so I used the info to log in and reset my account's password. Everyone should know that I didn't spend ANY time on the issue and only read about 2% of what the program had to offer. I zipped on through and decided it would be much faster to use what I learned from OPHCRACK to choose the Administrator login route. <br><br>This program probably works. Thanks!

    I am trying to recover the admin PW on my windows 7 desktop. I successfully booted from a CD with the ISO on it, but it did not recover any passwords. It took me to an orange desktop and asked me to choose a partition, I tried both and neither recovered anything... did I do it wrong? Then I tried doing it w/ the install version but it asks for a hash. I don't understand how I am supposed to provide a hash for the password if I don't know what the password is.....

    I burned the LiveCD to USB with Rufus, but my computer always says that the boot drive failed. I am trying to get into a Windows 8 machine.

    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!
