    Fault : Signed in with a temporary profile -- "You've been signed in with a temporary profile"
    Fix   : Repair the ProfileList entry
    Source: https://jbtecwiz.com/support/win-rec-profile-temp

    Run as     : Elevated PowerShell, signed in as a different administrator
    Expect     : 30 minutes
    Risk       : high
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    A local profile. The user's data is intact; only the pointer to it is
    wrong.

    HOW TO UNDO IT
    Import profilelist-backup.reg to restore the original entries.

    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.
