    Fault : STOP 0x00000133 -- DPC_WATCHDOG_VIOLATION
    Fix   : Find the offending driver in the dump
    Source: https://jbtecwiz.com/support/win-stop-0x133

    Run as     : Elevated PowerShell + WinDbg
    Expect     : 30 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    No obvious storage candidate, or the firmware update did not help.

    HOW TO UNDO IT
    Reinstall the driver you removed if it turns out to be needed.

    This script walks the fix one step at a time and asks before each
    one. Steps with no command are things you do yourself -- it prints
    those and waits. Run with -DryRun to print without executing.
