Fix 1: Delete the ScreenSaveActive Registry Key
If screen saver options are greyed out in Windows, incorrect registry edits are likely causing the issue. You must access the Registry Editor and properly edit certain keys to fix the issue.
Step 1: Press the Windows + R keyboard shortcut to open the Run tool, type regedit in the search bar, and click OK.

Step 2: In the Registry Editor, navigate to the following location:
HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\Control Panel\Desktop
Step 3: Right-click on the ScreenSaveActive string value > choose Delete.

Step 4: Click Yes to confirm your selection.

Similarly, delete the following string values as well if available in the same location:
ScreenSaverIsSecure
ScreenSaveTimeout
SCRNSAVE.EXE
Fix 2: Configure the Screen Saver Policy
Enable screen saver is an important policy that lets you change screen savers on your Windows PC. If you’ve mistakenly disabled this policy, you can’t change the screen saver and face various issues, including the one at hand. You may enable it from the Local Group Policy Editor.
Step 1: Press the Windows + R keyboard shortcut to open the Run tool.
Step 2: Type gpedit.msc in the search bar and click OK.

Step 3: In the Local Group Policy Editor, navigate to the following location:
User Configuration > Administrative Templates > Control Panel > Personalization
Step 4: Double-click on the Enable screen saver policy in the right pane.

Step 5: Choose Enabled > click Apply > OK.

Note: The Local Group Policy Editor is exclusive to Windows Pro, Enterprise, and Education editions. You may take a few extra steps if gpedit.msc is missing on your PC.
Fix 3: Update or Reinstall Display Drivers
Another prime reason behind the issue can be a corrupt graphics driver. The best way to fix that is to update the graphics driver or reinstall it. Here’s a step-by-step instructions to do that:
Step 1: Right-click the Windows icon in the Taskbar > choose Device Manager from the Power User menu.

Step 2: Double-click on the Display adapters.

Step 3: Right-click on the installed graphics driver and choose Update driver.

Step 4: Select Search automatically for drivers in the Update driver window that crops up.

Windows will now search for and download available graphics driver updates.
Alternatively, you may go through steps 1 and 2, right-click on the driver and click Uninstall device. Next, restart the computer to reinstall it.
You can also visit your graphics card manufacturer’s website (AMD, NVIDIA, or Intel) and download the latest update.
