How to disable the system beep sound in Windows
When you press the wrong key on a Windows PC, when an error dialog pops up or when you use the volume control, you hear a beep. After doing this a couple of times, that beep can get quite annoying. Therefore, in this tutorial, we will show you how to disable the system beep sound in all modern versions of Windows, to make sure that it remains silent and it doesn't bother you anymore. As you will see, there are two ways you can do this, both methods being relatively simple.
NOTE: This guide applies to Windows 7, Windows 8.1 and Windows 10. The procedure that applies to Windows 8.1 and Windows 10 is found on the second page of this tutorial.
Method 1: Disable the system beep using the Device Manager (Windows 7 only)
The first method is to use the Device Manager tool. If you want to learn more about this tool and how to open it, read this detailed guide: Find Missing Drivers & Hidden Devices in Windows with Device Manager.
Alternatively, you can open Computer Management and then click on “Device Manager" in the left column.
When the “Device Manager” is opened, click the View menu and select "Show hidden devices".
If this setting is not enabled, you will not be able to view the Beep as a device and disable it.
In the list of devices, look for the "Non-Plug and Play Drivers" category.
Expand it and find the Beep. Double click on it or right click and select Properties.
In the “Beep Properties” window, go to the Driver tab.
In the Startup section, click and then scroll down the Type list. Select Disabled and click OK.
Restart Windows 7 and the system beep is now disabled. If you want to stop it right away, click the Stop button in the Current status section, before closing the Beep Properties window.
In Windows 8.1 and Windows 10, the Beep is no longer listed as a device in Device Manager. Therefore, you can use only the method described on page two of this guide.
