OK, so you’ve muted your PC speakers, but you still get a beep from the computer when clicking on certain windows?
This is the internal built-in speaker included within your PC!
You can however disable this too…
Open Device Manager, then click on View and “show hidden devices”
Expand the group “Non-Plug and Play Drivers”
Double click “Beep”
Under properties, click the driver tab and then select Disabled for the “Startup Type” and then press the stop button.
Peace at last!
