Disable Windows Update entirely

What it does
Kills the update service so Windows never patches.
The honest verdict
Breaks Game Pass, anti-cheat compatibility, and security patching — and modern updates fix game-relevant bugs (fTPM stutter was fixed by an update). Pause or schedule updates instead.
How Compy treats it
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 Compy Blackbook holds 174 graded entries like this one, judged against your hardware — and every change it does make is reversible, with the receipt to prove it.
