Securely Prevent Changing The Screensaver

When the screensaver setting Is enabled, after a certain amount of Inactivity, It becomes active. That's until a given user utilizes the PC. Whilst screensavers were a requirement for old CRT monitors to prevent blurring of Images and text, they're not needed nowadays for LCD monitors and the like. Users however, commonly enable It for aesthetic and/or security purposes, hence In this tutorial, I will show you how to securely prevent your screensaver settings from being changed.

In today's computing standards, a screensaver Is predominantly used If a user wishes to password-protect their computer whilst they're away for a certain period of time. As such, the login screen will be displayed when Windows resumes It's session.

As already mentioned above, It's not needed for the latest display monitors, thus In this case, a screensaver Is active simply for entertainment purposes. Regardless of the reason why you've enabled yours, I will demonstrate how to securely and completely prevent your screensaver from being changed, by using the good old Group Policy Editor.

Do note that the Group Policy Editor, Is only available In Windows 10 Pro, Enterprise and Education editions. If you're running Windows 10 Home, you're out of luck. So without further delay, let's get this tutorial started.

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

Step Two:
The Group Policy Editor will now open, so navigate to the following directory.
User Configuration > Administrative Templates > Control Panel > Personalization

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

Step Three:
To the left of the window, select the Enabled radio button, and then hit OK to finalize the process.

Step Four:
Now let's test this, by navigating to Control Panel > Appearance and Personalization, and clicking the Change screen saver link as Illustrated below.

Last Step:
As you can see, the Display Control Panel where the screensaver setting Is located, cannot be accessed. Essentially, It's securely disabled.

Final Thoughts:
Just because you've set a password In your screensaver settings, by no means does It prevent anyone with the know-how, from circumventing It and disabling the password altogether. Or perhaps you're using your favorite screensaver for entertainment purposes. Either way, you'd want It's settings to remain as Is. Given the setting In the Group Policy Editor Is not well-known, It's certainly a secure way to prevent unauthorized changes.

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