I have boinc installed on my computer at home. I have Windows 10 installed. Is there a way to make the apps I install from the Windows store exclusive?

I'm not sure if the Store Apps can be located this way, but here's my 5 cents after searching a bit:

"Just open PowerShell with Administrator privileges, the type the below command and press enter

Get-AppxPackage -AllUsers | Select Name, InstallLocation
"

Then use mouse left button to "paint over" the InstallLocation path of an app that you were looking for and copy that chosen text with CTRL + C

Open File Explorer and put cursor to the address box or whatever it is called... and paste there. Then hit enter.

You should now see the contents of that hidden app folder. Look for 'application' type files. Maybe there's the executable file of that app that you want to exclude. If there is an executable that looks promising then you could try feeding Boinc 'exclusive applications' with that same path of that app folder.

The folders in which store apps are located have special security attributes which make it impossible for to BOINC open the executable files for execution, which is currently used to test whether they should be added as exclusive processes if selected. I've opened an issue on this problem.
