    Fault : STOP 0x0000009F -- DRIVER_POWER_STATE_FAILURE
    Fix   : Stop the devices most likely to be at fault from being powered down
    Source: https://jbtecwiz.com/support/win-0x9f

    Run as     : Elevated PowerShell
    Expect     : 25 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    Sleep or resume. This narrows it quickly without needing a debugger.

    HOW TO UNDO IT
    powercfg /restoredefaultschemes returns the power settings; re-enable
    adapter power management with Set-NetAdapterPowerManagement
    -AllowComputerToTurnOffDevice Enabled.

    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.
