tldr: MS Windows can be configured to trigger crash from PS/2 or USB or VM bus keyboard by 1) RCtrl+ScrLk+ScrLk, xor 2) combinations of (L,R)(Shift,Ctrl,Alt) + [KEY2] + [KEY2] e.g. LShift+RShift+Backspace+Backspace.
note: the `Dump2Key` keycode may differ from OS-reported codes on non-ANSI keyboards(ISO/JIS).
