The main innovation in the Disk Password Protection 5.1 is Hidden mode of operating system boot protection. No password prompt is displayed and the computer appears frozen, the computer will only start Windows (or any other operating system) after the correct password is entered and the Enter key is pressed.
It is easy to enable Hidden boot protection mode. Just activate the corresponding option upon boot protection enabling.
