You can easily get the screensaver off your computer by disabling it in Personalization settings. Search for Screensaver in the Start menu and open the Change screen saver you see in the results. Then, click on the drop-down button on the Screen Saver Settings window and set it to None. Then, click on Apply and then OK to save the changes. If your PC has any third-party screensavers, uninstall them as they overwrite the system settings to run the screensaver.
