It seems that on Windows 10 I cannot add new items to the "All apps" part of the Start Menu. I tried moving a shortcut to C:\ProgramData\Microsoft\Windows\Start Menu\Programs, but the program did not show up anywhere under the All apps view. Looking for the cause, I tried changing the name of one of the files already present in the aforementioned folder. To my surprise, the shortcut I renamed no longer shows up on the All apps view at all. Renaming it back to its original name did not bring it back. What could be causing this problem?
Update: Since I posted this question, I have noticed that the "Most used" applications are no longer updating.
Update 2: Since my last update, the issue seems to have somehow been resolved. I will look into possible causes for the resolution.
Programsfolder that appear on the Start Menu. I also just tried putting the shortcut I wanted to add into a new folder I created within theProgramsfolder, but this folder does not appear either. – Andrew Tapia Sep 18 '15 at 22:39
