    Fault : "Automatic Repair couldn't repair your PC" -- the repair loop
    Fix   : Read the repair log before doing anything else
    Source: https://jbtecwiz.com/support/win-rec-autorepair-loop

    Run as     : WinRE Command Prompt
    Expect     : 20 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    Always first. It costs twenty minutes and frequently names the exact
    file or driver.

    HOW TO UNDO IT
    Nothing was changed.

    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.
