Disabling the screen saver in Windows 11 can be done quickly through the system settings. The screen saver is technically disabled by setting it to “None” in the settings menu. Method 1: Using Windows Settings (Easiest Method)
Open Settings: Press Win + I on your keyboard, or right-click the Start icon and select Settings.
Navigate to Personalization: Select Personalization in the left sidebar. Go to Lock Screen: Click on the Lock screen option.
Open Screen Saver Settings: Scroll down to the bottom of the page and select Screen saver under “Related settings”.
Disable Screen Saver: In the “Screen Saver” dropdown menu, select (None) to disable it.
Apply Changes: Click Apply and then OK to save the settings. Method 2: Using Search Click the Search icon on your taskbar or press Win + S. Type screen saver. Select Change screen saver from the results. In the dropdown, select (None) and click OK.
Method 3: Via Local Group Policy (For Professionals/Pro Users)
If you want to enforce this setting for users on a pro machine, you can use the policy editor: Open gpedit.msc via the run command (Win + R).
Navigate to: User Configuration > Administrative Templates > Control Panel > Personalization. Set Enable Screen Saver to Disabled.
If you are trying to prevent the screen from turning off completely (not just the screensaver), I can show you how to change the power plan settings instead. Require a password when waking the computer. Customize the screensaver instead of disabling it.
