Top Secret: Windows 10 and the Frozen Desktop

Is it possible, if I take a screen shot of a Windows 10 desktop session with everything minimized and set that as the desktop background, to:

• make all real desktop icons disappear,
  
• hide taskbar so it stays hidden,
  

this would make it appear as if the mouse works but everything else does not respond on the desktop view when clicked?

Why?

I have a technical need to set up random desktop workstations in this manner for a special "top secret" project at work to see how certain employees respond and report incidents and issues for compliance adherence to a new company policy when malfunctioning systems occur.

Details

The computers are regular desktop computers with Windows 10 joined to a domian in an AD environment and I have full domain admin access to everything from login scripts, to GPO's, and on and on. I will accept and test all methods (scripts, Group Policy settings, manual steps on the desktop session doing this, and on and on) suggested to pick the best method for my need. Since I have a deadline months out for the first real run, I figured I'd ask some experts or regular people for some suggestions on this task.

Undo Optional

If you have a method to undo this for the method you advise that would be great but it's not required and I'll figure that part out but the easier for me the better for setting it up and undoing it for all methods I'll test.
