Hi @pelaird, This is a regular desktop fence.
The way I created them a long time ago is to right or left-click anywhere on the desktop and select Create Fence but that option appears to have disappeared - very strange
The missing icons are placed in my "junk" fence. This is my default behavior when software is reinstalled/updated and new icons are created, I then drag to the fence I want the icon in
NOTE: On my machine I went to Control Panel\All Control Panel Items\Programs and Features and Fences 5 was updated on 5/23/2024
OS Build - 19045.4412 Windows Feature Experience Pack 1000.19056.1000.0
Thanks
