To disable them, click the Sound settings tab and uncheck 'Enable notification sounds.' ScpToolkit starts up with Windows by default, and also plays some sound effects that you might find obnoxious. Most of these settings you should be able to leave alone. Here you can change some settings like disabling rumble, adjusting analog stick deadzones, and more. Look in your Start Menu for ScpToolkit Settings Manager. Now that it's installed, you'll see ScpToolkit as an icon in your system tray.
