When I start any Windows 8.1 Modern-UI app, it may notify me that the app need update.
Thus, to use it I have to update the app, but this is troublesome if I don't want to update the app (at that time).

Thus I must update it to use it.
How can I stop these in-app update notifications, and/or is there a way to disable them from checking for new versions?
NOTE: I have disabled auto-update of Windows Store apps via group policy and via the Store app.
I have also considered that it may be possible to reset to 0 the number of app updates available. For that I have tried setting the following registry key to 0, but without any success:
