Windows Update keeps updating after being disabled

I got 3 black screens after Windows Update, first one after 3 weeks of use.

Now I’m tired of this and I want to disable it for good.

I disabled the service, the temporized task and even the registry key but it keeps updating.

Updates are not safe anymore, they create issues worse than the one that solves.
I have a Retail license and the updates seem to be in Beta or Alpha state, I’m not a Beta tester.
