    Fault : STOP 0x00000133 -- DPC_WATCHDOG_VIOLATION
    Fix   : Update SSD firmware and the storage controller driver
    Source: https://jbtecwiz.com/support/win-stop-0x133

    Run as     : Windows
    Expect     : 30-60 minutes
    Risk       : medium
    Reversible : NO -- read the undo note below before running

    WHEN THIS IS THE RIGHT FIX
    There is an SSD present. Firmware updates cannot be undone, so back up
    first.

    HOW TO UNDO IT
    Firmware cannot be rolled back. Drivers can, through Device Manager ->
    Properties -> Driver -> Roll Back Driver.

    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.
