If you ever get annoyed from that beep you hear every time you push down more than one key by accident? Or maybe it happens when your PC freezes and you can’t push any key without hearing it. Well, here is how you disable the sound:

1.) Go to “Start–>Run” and type “Regedit” in the command prompt. Then hit OK.
2.) Navigate to “HKEY_CURRENT_USER\Control Panel\Sound”
3.) Right click on “Beep” on the right side of the screen and select “Modify”
4.) Change the value in the box to “No”
5.) Exit and reboot the computer.

Voila! No more beeping. If you ever need to re-enable it for troubleshooting, just do the same process, but change the value to “Yes”. This tip works with Windows XP and may work on older versions as well.
