    Fault : STOP 0x0000009F -- DRIVER_POWER_STATE_FAILURE
    Fix   : Name the driver from the dump
    Source: https://jbtecwiz.com/support/win-0x9f

    Run as     : WinDbg
    Expect     : 40 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    No pattern, or the quick fixes did not help. For 0x9F the dump
    identifies the device stack precisely.

    HOW TO UNDO IT
    Roll the driver back in Device Manager if the newer one is worse.

    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.
