If you have items pinned to the start menu and you get a security popup when you try and run them that looks like this, this will usually be from a network share, but can occur from any folder:
Navigate yourself to this folder.....bear in mind the section in fuchsia will be hidden so if you do not have "show hidden files and folders" enabled in your explorer options you ill not see those folders.
%userprofile%\AppData\Roaming\Microsoft\Internet Explorer\Quick Launch\User Pinned
Then once there you will need to run this command from that location........
icacls "*.lnk" /l /SetIntegrityLevel med
