      I checked out Device Manager and found out that in my laptop it’s PS/2. I had so much fun crashing my computer afterwards! I was even offered to enter recovery mode after several crashes!

    This doesn’t seem to work on my Windows 10 Anniversary Update installation.
    When I use the key combination, the system just freezes and has to be force restarted, there is no BSOD shown.
