Windows 10 - Everything appears in the top half of my screen

Hey, I believe one of my children touched my laptop and now almost everything appears in the top half of my laptop screen.

For applications where I have a minimise/maximise, I was able to click normal and then maximise and this worked fine. For all other windows functions, they appear in the top half.

Even then, applications like outlook are not working properly. As an example, the reading pan in outlook (when showing to the right) only appears in the top half. If I open an email so it appears full screen. the bottom half of the screen remains blank
and I can only see the email in top half. If I click normal, it does the same but worse.

Any help is appreciated. Photo's below:

Same email when normalised

 

Windows 10 Tweaks

As you may already know, Windows 10 (as well as Windows 8) allow you to log in with a valid Microsoft account, instead of creating a local account that only works on your machine. However, you may prefer to keep a local account for privacy reasons. If you do, though, some Windows 10 features—like Cortana—may not work. Despite the default behavior, the Windows 10 Store is not one of them. You can still log in to your Microsoft account for just the Store without switching to a full Microsoft account. The process, however, is not terribly obvious. To do so, follow these steps:

• Launch the Store from your Start menu.
• Click the user icon next to the search box.
• Click “Sign-in” from the menu that appears.
• Choose “Microsoft account” and log in like normal.
• When the “Make it yours” box appears do not enter your password. Instead, click “Sign in to just this app instead.”

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.
