Do I need to keep the UWP app running to show the Explorer Context Menu?

Will the context menu show up only when the UWP app is running in the background for the same user which started it?
What if I need to register a context menu for ALL USERS for an app that will be started by the Com DLL?

Prob a bit late, but from my tests, don't think you need to keep it open. once it gets registered, dllhost.exe seems to call the dll defined in the appxmanifest, and adds in the menu even if the application isn't actually running
