If you are one of those who easily get nervous with all kind of error sounds, turning off/on the sounds of Windows and similar, the “problem“ can easily be resolved by turning them all off. All sounds of Windows will be turned off (that means error sounds, warning sounds, information sounds, turn on/off sounds and similar). Of course, the sound system in Windows that you normally use is still available (playing music/movies and similar).
All you need to do is go at Start – Control Panel – Sounds and Audio Devices. Choose Sounds tab.
Under Sound sceheme: choose No sounds. You’ll get a warning about saving last changes/preferenecs, simply click No.
Apply i Close.
