Yep, but medicat lists (among other tools) the PEPassPass (which is a derivative of PassPass), all those tools need to boot into an Operating System (a PE or a Linux), change something, then reboot to the "normal" OS.

What is (was) elegant in the grub4dos PassPass is (was) that you booted to grub4dos, ran the batch and then continue booting to the "normal" OS.
