Taskbar isnt hiding

The windows 10 taskbar wont (Frustratingly) hide when I do anything fullscreen related. For example, In youtube it goes fullscreen, but the taskbar wont hide. Same thing with games or anything fullscreen related. one example of "Anything fullscreen related"
is a common steam game : Unturned. the taskbar wont hide during fullscreen mode. Also, Please do not suggest auto-hide. auto-hide is as cancerous as the problem itself, In my opinion.

 

Taskbar not hiding when I enter fullscreen mode with windows store apps

No, I don't want to hide the taskbar for the majority of the time, only when I go fullscreen it usually just disappears and the app goes fullscreen. Is there another option apart from auto hide taskbar in desktop mode?

 

Taskbar not hiding when I enter fullscreen mode with windows store apps

When I enter fullscreen mode with windows apps they still show the taskbar and the little bar at the top of the screen. I know about auto hiding the taskbar when in desktop mode but this is not what I want to do, only when in fullscreen mode. It was working
perfectly fine but all of a sudden it will not work.
