    WARNING: DO NOT RUN THESE TESTS ON A VALUABLE MACHINE!
    Running on a disposable VM or AppVeyor is strongly recommended.
    If these tests go awry, your machine's registry could be corrupted which will brick your machine!
    If this happens to you, it is fixable, but the fix is difficult and time-consuming.
