I would like to know how to clear out the Show Notification from These Apps section as well because mine has duplicate apps and some that are not even installed any more! Typical that Microsoft would include these but not give us an option to delete them individually by simply right-clicking on each one and selecting Delete (it's similar to the horrendous issue I had trying to remove an expired and long deleted appointment from my Calendar... that was extremely awkward to fix such that I no long use Cortana to make appointments any more!!!).
Have you tried with Ccleaner then go to
Tools uninstall
That will normally get rid of left over bits if it still shows up in there
If none of that works
Try Revo Uninstaller
You can use the 30 day trial
Also make sure you read it though and understand it
I Liked it so much on all my systems I pay for it
If you have time and wouldn't mind doing a Repair Install..................
