While the use of such beep sounds can be dated back to olden days when computers didn’t have sound cards but just built-in speakers producing various beep sounds to notify the troubleshooters help diagnosing the issues. Well, the times have changed, even though the desktops and laptops ship with internal speakers producing beep sounds, they are hardly useful when you are using advanced operating systems like Windows 7 as we have more sophisticated diagnosing mechanism to troubleshoot the OS issues. Too many beeps, you would easily get annoyed. Follow these steps to disable the system beep sounds in Windows 7.
