Weird Windows 10 Notification Items

[xWhiplash]

Does anybody have Notification entries like Microsoft.Explorer.Notification.{04532145-411B47-54110}?

I have two of these.  Does anybody know what they are?

 

I found them in Settings - System - Notifications & actions

Is this on a fresh or upgraded system?

I saw several of these in some of the insider builds, they would also appear in the startmenu as tiles. I think most of those bugs have been fixed by now...

Fresh, I did a clean install.

Yes. I have one. It seems a lot of people have this issue even on clean installs but nobody knows what is causing it. It sucks that the interface won't let you go to the file location of the application the entry is for.
