    Fault : 0x80090016 -- Windows Hello and the TPM: "Something went wrong, your PIN isn't available"
    Fix   : Rebuild the Ngc credential container
    Source: https://jbtecwiz.com/support/win-tpm-hello

    Run as     : Elevated PowerShell
    Expect     : 20 minutes
    Risk       : medium
    Reversible : NO -- read the undo note below before running

    WHEN THIS IS THE RIGHT FIX
    The usual fix. Everyone on the machine will have to set their PIN up
    again, so make sure a password sign-in works first.

    HOW TO UNDO IT
    None -- the old credentials are deleted. The account password is
    unaffected.

    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.
