    Fault : System Restore has no restore points, or restore fails
    Fix   : Turn protection on and give it enough space
    Source: https://jbtecwiz.com/support/win-rec-restore-missing

    Run as     : Elevated PowerShell
    Expect     : 15 minutes
    Risk       : low
    Reversible : yes

    WHEN THIS IS THE RIGHT FIX
    There are no points at all.

    HOW TO UNDO IT
    Disable-ComputerRestore -Drive 'C:\' turns it off again and deletes the
    points.

    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.
