Windows has not given me any "important" notifications for several months. Never minded, but a few days ago I bought Forza Horizon 3 to play with friends. The problem came when they invited me and I did not get any kind of notification, whereas if I invited them, they got a notification. These last 4 days I've been trying to find the problem until I found it. On Configuration -> System -> Notifications and actions, notifications are enabled, but I only have some of the many applications that should exit me (See the Screenshot):

Then I asked my friends what where the apps shown on that section. They told me a list of applications and they all agreed on one, the Xbox App. If this is activated you'll get the notifications, but of course, I do not even get the Xbox app in this section = /For example, you can see how I have the Store option enabled, and when I download a program from the Store I get notification. So Windows notifications work correctly, but Windows does not detect many Apps = (

I have tried several solutions like:· Run Toubleshooter from Windows Store apps· Run the sfc / scannow command on CMD· Trying to change values in Regedit without success· Apply the fix "AppDB Registry Import for Fixing Missing Notifications" (With this was hoping to fix it but did not solve anything)

And a lot more of "fixes" unsuccessfully. The last option will be to reinstall Windows, but I want to avoid this as much as possible = /

If anyone knows how I could fix this, I would appreciate if you share your possible solution =)
