To disable globally or for individual apps, i.e. to prevent "UWP Apps" from running on their own in background:

Go to "Settings -> Privacy -> Background Apps (scroll down to it) ...

From there you can disable each app individually with the toggle beside the app name, or - if I read it correctly - you can flip the top-most toggle to OFF, "Let Apps run in the background". With this set to OFF, then none of those apps should run or be launched for the stated "UWP" reasons of maintaining their versioning and etc..

So disable individually or via the top-most toggle - to OFF. Again, that is:

Settings -> Privacy -> Background Apps then toggle to OFF for specific apps or turn "Let Apps run in the background" to OFF.

From there you can disable each app individually with the toggle beside the app name, or you can flip the top-most toggle, "Let Apps run in the background", to OFF to globally disable.

@john - UWP is a Windows 10 FEATURE, not a separate 3rd party app. Win 10 feature "Universal Windows Platform" is a mechanism for controlling run-states of background applications. "... an application you installed" is totally wrong.

UWP is a Windows 10 FEATURE, is is not a separate 3rd party app - check your info. UWP is part of the Windows 10 OS now... and it is bugged, for sure, imho. It has been suspending active applications like video-players (e.g. VLC) even when not registered in a UWP group.

@John - You probably should not say it is a 3rd party app, it is a semi-recent Win 10 feature called "Universal Windows Platform" and is a mechanism for controlling run-states of background applications. "... an application you installed" is totally wrong.

From what I see, to prevent "UWP Apps" from running on their own in background, go to "Settings -> Privacy -> Background Apps (scroll down to it) ...
