Disabling windows updates for windows 10

Starting with windows 8 I have many many many hardware issues (that are not present in Windows 7). One of these issues is the fact that an initiated restart does not work. It shuts down, the bios shows up, loads, then the windows boot loader begins loading and suddenly the progress ring halts and nothing happens anymore (I have tested it for several hours). While this is not really a problem usually (If a service attempts to initiate a restart I just pull the power after saving everything) with windows 10 it became a problem. A while ago obviously a new build was released and it tried to install said build. This is done using an initiated restart. The restart happens, it hangs in the boot loader and when I reset the machine I get the usual "Your windows has been reverted to an earlier version" message. So far so good. The problem is that since then every day this happens. It randomly asks me if I want to apply the update now, I obviously dont want it to, and set it to remind me again in 8 hours. I dont know what insane person had the idea that a forced shutdown that kills every living thing on your computer was the appropriate action for something as utterly unimportant as an update but sadly after these 8 hours it does exactly that.

After loosing a several gb download and a very long compilation has been corrupted I'm now ready to do everything to stop this madness. I first tried it the nice way and checked the update settings. Windows responds witht he following:

A note here: I am the system administrator, this is a home computer and I am on the only account there is. How do I get rid of this non-sense?

Next I tried to forcefully kill the entire update service. It seems it worked for regular updates, but the preview build update is something that is not covered by that. When I go to the settings for new build installations all I am able to change is the time new builds should be installed (if available). Is there a way to completely disable that?

So to summarize: Is there a way to prevent windows from performing any action if there are updates? Or disable updates completely? Making everything manual? In the end the updates have destroyed more on my computer than they have prevented.
