    Fault : STOP 0x00000133 -- DPC_WATCHDOG_VIOLATION
    Source: https://jbtecwiz.com/support/win-stop-0x133

    This script CHANGES NOTHING. It runs only the inspection commands
    from the write-up -- the Get-, Test- and Resolve- calls that
    establish which cause is in play -- and prints what each returned.
    Anything that writes, deletes, starts or stops is excluded by
    construction, not by judgement.

    Read the output alongside the write-up, then pick the fix that
    matches. Each fix has its own script on the same page.
