I changed the location of a user's personal folders to a mounted network drive, by modifying the values under HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Explorer\User Shell Folders. After restarting explorer, the folders are moved as expected in Quick access only. If I go to the folder from "This PC", the old location is used. If I change the location of the folder manually, (right click > Properties > Location), it works fine.

How can I change the location of the user's personal folders so that the changes apply everywhere in file explorer, including "This PC"? (I'm using Windows 10 Professional)
