Somehow my latest work laptop (Dell Latitude D620) has a PC speaker circuit that bypasses mute settings and the headphone jack. Windows loves to BEEP on certain events, whether it's just control-G ASCII characters in the console, or a bell in a PuTTY window.
The quick solution is to run the secret: "net stop beep". That stops the secret beep service from running.
But a more permanent fix is to go into the Device Manager (Control Panel -> System, Hardware tab, then the Device Manager button). In the View menu, pick "Show hidden devices". Now down in the treeview, under Non-Plug and Play Drivers, there is a "Beep" driver. You can change the properties on it to disable it and stop/disable the service. Ignore the prompts to reboot now.
That's it. No more beeps. Well, unless you run VMWare. See my other post about that.
