So my roommate, who uses windows 7, has locked herself out of her computer. The folks over at the windows 7 subforum have been talking me through downloading ophcrack and trying to put it into a USB with my MacBook Air.
Our progress is here: http://www.bleepingcomputer.com/forums/t/528137/locked-out-of-administrator-account/
However, I have been unsuccessful in using the terminal to get the program onto a USB. I wonder if someone would be able to take a look at the other forum and help me with this part?
