    Fault : Signed in with a temporary profile -- "You've been signed in with a temporary profile"
    Fix   : Deal with a roaming profile that will not load
    Source: https://jbtecwiz.com/support/win-rec-profile-temp

    Run as     : Elevated PowerShell
    Expect     : 45 minutes
    Risk       : medium
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    Roaming profiles or a session host.

    HOW TO UNDO IT
    The profile on the share is untouched by these steps.

    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.
