I followed the instructions and then restarted all 5 of my computers and the shortcut arrows were gone.Run Registry Editor
Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer
Right Click Explorer Folder and choose New Key
Select the Key and name it Shell Icons
Right Click Shell Icons and select New and then String Value and type 29 as the String Value
Double click 29 and Enter %windir%\System32\shell32.dll,-50 in the data value.
Exit Registry Editor and Restart computer
I turn my machines off at night 2 of them are Win 10 Pro, 1 is Win 10 Home, and 2 are Win 11 Pro. When I turned them on this morning, every one of them showed a big black square box where the shortcut arrows used to be. On one machine that box was nearly the size of the icon itself. So luckily I was able to reverse this problem by deleting that newly created Shell Icons Key. Since this happened on all my machines regardless of the OS, surely others must have had similar experiences. Why would this happen and is there something else I should have done to get rid of those shortcut arrows?
