Windows 10: Problem with multiple screens and wallpapers

Guys please help me on this one.... It's driving me crazy and I just can't for the life of me figure it out...

After booting into Diagnostic Mode (msconfig) once, whenever I try to pick separate wallpapers for my screens I get this:





Same thing happens when I go through the old interface of control panel:





If I disable any screen from Nvidia's control panel, both options are gone and won't return even after I re-enable the screen unless I reboot. If I unplug one screen it changes to "Set for monitor 1" again showing up twice.

I'm at a complete loss here, usually I can fix those weird bugs but this one is driving me crazy to the point that I'm considering restoring from backup but I really want to avoid an extra 70gb worth of writes to my SSD.

edit: For what is worth, this is a UEFI install and running the latest build

Where to get Windows desktop images - like the ones shown on login.

If you meant different virtual desktops, then it's not possible to assign different wallpaper for each virtual desktop.

For multiple-monitors, you can. See
