Force program to run as a normal window.

[DraconisMaximus]

Does anyone know of any way to truly FORCE programs / apps to run as a normal window.
Ideally something through integrated settings whether: Control Panel, Group Policy, Registry, etc.
I would prefer to avoid fixing with yet another piece of software.

I am currently running Windows 10 Pro.

 

The program I am currently having issues with is Emby Theater though i have had the issue with other software in the past.
It spawns as a pseudo window which ignores commands like [Windows Key] + [Arrow] for window manipulation.
The "Maximize" button is actually a fullscreen button, so it cannot be maximized or snapped to the side.

The Emby developers helpfully claimed they "are working on an all-new windows app to replace it that will be more like a normal windows app."
I have no idea why anyone would go out of their way to create such a bizarre mechanic in the first place.

 

It does seem however that Windows itself should be able to exert some level of over the way things display regardless.

Any constructive ideas appreciated.
