How can I suppress the standard machine beep noise in Windows 2000 and later?

A. Even if you mute your system, certain events will still trigger the system beep. To suppress these system-level beeps, perform the following steps:

1. Start a registry editor (e.g., regedit.exe).
2. Navigate to the HKEY_CURRENT_USER\Control Panel\Sound subkey.
3. Double-click Beep, set the value to "no", and click OK.
4. Close the registry editor.
5. Log off and log on for the change to take effect.
