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 you can flip the top-most toggle, "Let Apps run in the background", to OFF to globally disable. With this set to OFF, 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.

This most probably indicates that the related hardware driver or the hardware itself is buggy. As mentioned in the Old New Thing blog (linked in the Cannot end Windows 7 process, even tried pskill question):
I've seen this problem happen in drivers that I wrote myself (during debugging), and the only way to handle this is to unlod the problematic driver and hope that it will clean up after itself on unload:
net stop drivername
for software-only drivers, if they are loaded on-demand.If you cannot do this, or unloading the driver fails, then only reboot option remains.
