Securely Prevent Changing Lock Screen Image

Irrespective of the type of computational user, be It navigating on Facebook and YouTube or processing reports for work purposes, everyone customizes their PC to some degree and as such, would want their settings Intact. Part of this equation for many users, Is the Windows 10 "Lock Screen Image", that can be changed by anyone with a few clicks of the mouse. In this tutorial, I will show you how to securely prevent changing the Image.

Before I make a start, here's what I'm referring to, namely the Windows 10 Lock Screen Image. As you can see, the background can be changed with anything you like.

If you've customized yours, then you'd know exactly what I'm on about. To securely prevent every user from altering It, I will be using the good old Group Policy Editor, which Is a native utility In Windows 10 Pro, Enterprise and Education editions. On the grounds you have either of these editions Installed, then this guide Is for you. So let's get this started.

Step One:
To access the Group Policy Editor, open the Run menu, enter gpedit.msc and hit OK.

Step Two:
Next, navigate to the following directory:
Computer Configuration > Administrative Templates > Control Panel > Personalization

Then on the right pane, double-click Prevent changing lock screen Image.

Step Three:
To the left of the window, click the Enabled radio button, and then hit OK for the change to take effect.

Step Four:
Let's put this to the test. Open Windows Settings, and click on the Personalization option as shown below.

Last Step:
I've now clicked on Lock screen, and as you can see on the right-hand side, the Background drop-down menu Is grayed out. Essentially, the Image cannot be changed. This Is confirmed by the message In red, namely Some settings are managed by your organization.

Final Thoughts:
If you have multiple users utilizing your computer without a dedicated local user account, then they can basically do as they please with It's options and settings. Whether It's Intentional or by accident, you'd want the Lock Screen Image to remain unchanged, particularly If you've applied It with one that you can no longer access.

To reverse the change and have the Lock Screen functioning as per It's original state, go back to Step Three above, select the Not Configured radio button and hit OK.
