If you are using the popular accounting software Tally, you might get irritated with a beep sound that plays every time you save the voucher or when you press escape keys to exit tally. It beeps even if you mute your system speakers, and in a quiet office environment, that irritating sound is heard more prominently. One temporary solution to this is to press CTRL+A key to save the voucher without prompting. You need to press this key when you have completed the voucher entry.
However, I found a permanent solution to this problem which I am going to share with you with screen shots from Windows XP. For Windows Vista and Windows 7, solution is quite similar.
First you need to right click on "My Computer" and go to properties. Go to Hardware tab and click on "Device Manager".
Click on "View" button from main menu and select "Show Hidden Devices" option.
Find and expand "Non-plug and Play Drivers" from the list below.
Right Click on "Beep" and Disable it.
If you are prompted for a reboot, select no and then again right click on "Beep" and go to Properties.
Go to "Driver" tab and change current status to "Stopped" and select "Disabled" from the "Startup" dropdown.
Then reboot if you were asked earlier, and now you would be free from that irritating beep in Tally.
