What is a PC speaker?  It is a small speaker located inside a majority of desktops and laptops.  In the early days of computers these where the only source so sound from your computer.  In the late 1980’s computers started to have dedicated sound cards that produced much better sound.

Even today there still a use for the PC speaker.  It is primarily used for diagnosing hardware issues with a computer.  Some application developers still use the PC speaker for notification of an event.  If that event happens often it can get quite annoying to hear the beeping all day.  Here is how you can disable the speaker in Windows without modifying any hardware.

To Temporally Disable the PC Speaker

Go to the run command in the start menu.  In the run command type “net stop beep”.  Then click on OK.

To Permanently Disable the PC Speaker

Go to the run command in the start menu.  In the run command type “net stop beep”.  Then click on OK. Then go back to the run command and type “sc config beep start= disabled”.  Then click on OK.

That’s it.  You will never have to listen to the beeping again.  Just a note, if you are not the administrator of that computer you may not be able to perform this action.  It depends on your permissions.
