What it does
Kills the update service so Windows never patches.
The honest verdict
Graded risky. Breaks Game Pass, anti-cheat compatibility, and security patching — and modern updates regularly fix game-relevant bugs and stability issues. Pause or schedule updates instead.
It's on Compy's refuse list. Compy will never apply this tweak — and if a guide already talked you into it, reversibility is the whole point of the app.
The full graded entry
This entry ships inside the app, cross-linked to every related verdict in the graded book. The Blackbook publishes its verdicts here — the full write-ups stay in the book, on your rig, next to your own measurements.
The Compy Blackbook holds 191 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
