Windows 10: Disable fullscreen optimizations for everything?

Is it possible to completely disable fullscreen optimizations with one setting instead of clicking on every game executable I have?

:)

 

Can't disable 'Fullscreen optimizations' globally after October 1809 update

I have always disabled Windows 10's Fullscreen optimizations. Even if some people say the new 'fullscreen' presentation mode offers better performance and quicker alt-tabbing, I still disable it. I have my reasons. I want all of my games to run in
Exclusive fullscreen mode. And for me, the registry entry, 'GameDVR_FSEBehavior' set to '2' always disabled Fullscreen optimizations globally (no need to go into each .exe's Compatibility settings to disable it).
Located in: HKEY_CURRENT_USER\System\GameConfigStore

Now, after the 1809 October feature update. The fullscreen optimizations presentation mode defaults to on in all games, regardless of the 'GameDVR_FSEBehavior' value. The other method of disabling it globally has also been gone for a few months now. Unchecking
the box, "Show game bar when I play full-screen games Microsoft has verified" used to disable Fullscreen optmizations globally, but that setting was removed from the Gaming options in Windows.

I would like to know how to disable the Fullscreen optmizations presentation mode
globally in Windows 10 after the October 2018 update.

I do realize that individual .exe's can disable Fullscreen optimizations by right-clicking, Properties, and going to Compatibility tab, but even this solution doesn't work for all games now.
For example; after the October update, I have yet to find a way to disable fullscreen optimizations for Fortnite BR. Even with the option checked in the exe, it still runs in the 'enhanced fullscreen' mode. I cannot find a way to run Fortnite
BR in exclusive fullscreen after the October update 1809.

Thanks!
