My DC is Windows S2008 r2 and i have a wallpaper policy set for all domain users. It works fine and the wallpaper shows up on all client computers. I want to modify this so that my Windows 10 clients (or any really) can change the background if they want to. I tried the recommendations in this link but they don't work for Windows 10 clients.
Here is screen shot when user tries to change background picture (greyed out).
Is this customization via gpo possible?
