Cool tool I used a similar utility years ago on my laptop when I spent time in coffee shops. It's very convenient to just pull out the flash drive to lock the system when you need to walkaway from the computer for a minute.
and why not just use a password for ur windows account and bios if anything, someone can exploit the usb raptor program and make a usb that unlocks all usb raptor-locked computers, completely bypassing your security oh also what if you spill smth on ur usb or u lose it or someone steals it?
