The way to control which updates you get and don't get is to stay with an earlier version of windows. I do not know if a tool exists to give users control of updates in windows 10, and if one did then I couldn't be sure: whether it was actually effective(as in whether it would actually give users control or whether it would merely appear to), whether it was safe (as in not some sort of virus ir PUP in disguise) or whether it wouldn't lead to other problems (it is certainly conceivable that preventing updates could lead to problems on windows 10, because it expects all of them to be installed). If such a tool existed/exists then it certainly wouldn't be coming from MS, it would be a third party thing.
If you want to keep control of updates then I suggest:
..If you are thinking about "upgrade" I suggest you stay with your current earlier OS.
..If you have already "upgraded" then I advise that you look into options for going back to your previous OS.
..If you bought a computer with windows 10 preinstalled I suggest you contact the shop/manufacturer and ask about the possiblity of downgrade to windows 7/8/8.1, ask about whether your hardware would be linux capable or ask whether you can return the device get a refund and buy yourself something with windows 7/8/8.1 with the money you get back.
By using a previous OS then you can control which updates you do and do not get, if you want to avoid windows 10 make sure to set your updates to "check automatically but ask me whether I want to download" and do not ever install KB3035583 or KB3044374.
If you need any more information or advice (advice on what to do or advice on how to do it) the people on this forum are very happy to help you.
