there is an easy fix to that
sadly its a german site which explains how but im sure there is a english one too
just google the problem.
in case there is no english one for that here is the german one (the ui is the same for every windows 10 basically so just go with the pictures not the text in the Part 1. In order for you to know which is the First Part = it says Teil 1 at the beginning of the text and it ends after the pictures when it says Teil 2 (Part 2). Ignore Part 2 (Teil 2) since this has nothing to do with it.
Anyway to explain it short its about how to get the rights to show whats inside and to delete it, this is what you need for everything that has such issues.
BUT apparently they say if the folder is in your maindrive (most of the time called c) do NOT delete that Folder, only a Sub-Folder when you know its not System related.
I hope that helps some people here
EDIT: here is a how to in English you dont need to download anything just scroll a bit down and they explain how to do without downloading their tool http://www.minitool.com/data-recovery/delete-access-windowsapps-folder.html
