How please can I change the sound when someone logs onto Messenger? And also how can I silence the mouse sound, when I adjust the volume control to the speakers on-screen? I have tried various items in settings - sound - sounds, but to no avail. Any advice much appreciated.
C/P sound, speech and audio device, sounds and audio devices, sound tabs, scroll down to windows explorer. click on 'start navigation'. In the 'sounds:' box (below) click on arrow to expand. Choose different sound or 'none'.
