256986 Description of the Microsoft Windows Registry



INTRODUCTION
This article describes how to turn off the beep sound that a virtual machine generates every time that an operating system event occurs. For example, if you try to log on to a virtual machine by using incorrect credentials, the virtual machine operating system generates a beep sound.



MORE INFORMATION
To turn off the beep sound, use one or more of the following methods.

Method 1: Turn off the beep sound on a particular virtual machine
Warning If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.

To stop a virtual machine from generating a beep sound when an operating system event occurs, follow these steps:  On the virtual machine, click Start, click Run, type regedit in the Open box, and then click OK. Locate, and then click the following registry subkey:

 In the right pane, right-click Start, and then click Modify. In the Value data box, type 4 to turn off the beep sound, and then click OK. Quit Registry Editor, and then restart the virtual machine.

Note You can also follow these steps to turn off the beep sound on the host computer. In this scenario, the beep sound is also turned off for all guest operating systems.

Method 2: Turn off the Beep service
You can turn off the Beep service in Microsoft Windows XP or in Microsoft Windows Server 2003. To do this, type the following command at a command prompt, and then press ENTER:

sc config beep start= disabled

Note You must include the space after the equal sign (=).

To turn the beep sound back on, type the sc config beep start= command together with one of the following startup types: 

boot

system

auto

demand

Method 3: Stop the Beep service
You can stop the Beep service by using the Net command. However, in this scenario, the service automatically restarts when you restart the virtual machine or when you restart the host computer. To stop the Beep service, type the following command at a command prompt, and then press ENTER:

net stop beep

To start the Beep service, type the following command, and then press ENTER:

net start beep
