The bootlock thing is easy to overcome. I had to fix a neighbour who got scammed. It is a password on the Windows registry not actually the boot but it needs to open the registry to boot.
Windows backs up the registry. Just boot from a WindowsPE or live Linux USB and delete the live versions and replace with the backups. Reboot and lock is gone.
