Had uninstalled all products to go through a few W10 update cycles to see if old issues improved. Got an email for DS10 so I reinstalled Desktop Object Manager and from there installed DS10, fences, an some others.
When I rebooted the old fence boxes were displayed. When I first clicked them they disappeared, AS DID ALL MY ICONS.
So now I have only the most recent icons on screen. ALL the others are gone.
