For example, you might want to disable “Notification” sound effects while leaving “Critical Battery Alarm” sound effects enabled. You can also choose to disable sound effects for specific events. On the Sounds tab, click the “Sound Scheme” box and select “No Sounds” to disable sound effects entirely. If you also want to disable the sound that appears when you sign into Windows, uncheck the “Play Windows Startup sound” checkbox. You can also just navigate to Control Panel > Hardware and Sound > Sound. To open the Sound control panel, right-click the speaker icon in your system tray and select “Sounds”.
