Active hours setting in updates do not work. It is only a "guideline" which Windows 10 does not have to follow. Internet is full of people complaining about restarts during active hours but Microsoft knows what is the best for us.
The only thing that seem to work is setting the connection as metered. It won't download any updates then. Every now and then I change it back to metered, get updates and then change it back. This is of course followed by changing back the settings that the update changed as, again, Microsoft knows what is the best for us.
As you said, Win10 needs to be slapped back into line every few weeks. It should not be that way.
I would say it is not a well meaning kid but a bully, trampling all over our choices
