    Fault : "The User Profile Service failed the sign-in"
    Fix   : Create a fresh profile and migrate the data
    Source: https://jbtecwiz.com/support/win-profile-service

    Run as     : Windows
    Expect     : 30-60 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    The profile folder is gone or the registry repair did not take. Do not
    delete the old folder until the new profile is confirmed working.

    HOW TO UNDO IT
    The original data is still in C:\Users\olduser.broken until you remove
    it.

    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.
