The Toms Guide one may not work for everyone. In my experience, disabling the windows update service is a Band-Aid and can undo itself eventually, especially if you leave it on manual, and then update yourself (which you should frankly, periodically do, in particular if this is a computer that does internet browsing or has other day to day functions) since some windows updates will try to restore it to it's intended state.
If you're on Pro, you should have access to Group Policy controls in GPEdit.msc , the things to disable are in there. If not you can change that 'pause' update counter to an arbitrarily high value in the registry (just google to see where the key is). OOBE is also something you can nuke out in GPEdit if you end up getting that nag screen on boot occasionally. Why OOBE (or frankly a number of things) is on by default in enterprise installs by default I'll never know.
Disabling Windows 10 updates is somehow, an ever changing process, however, as I mentioned, there is a value to updating on your terms.
