Turn Off the PC-Speaker

 Did you ever get annoyed for that beeping sound from your Windows Machine, especially when you're in office or some other public places? You mute all sound devices but it didn't work. Here is how to turn it off.

 
当你正在办公室或者其他地方使用电脑，但突然它发出尖锐的"嘟嘟"声。 非常恼人，不是吗？你将所有设备都设为静音，但仍然无济于事。这里我们有一个办法来关掉它。

  In Windows 2k/XP,click "start >> Run", key in "devmgmt.msc" and press "Enter" to go into device manager, select the "Show hidden devices" option in the "View" menu, go to "non plug and play device" find that device named "Beep" and set it to disabled.

在Windows2k/XP中，点击"开始>>运行"，输入"devmgmt.msc"，在弹出的设备管理器窗口中，点击"查看"菜单，选中"显示隐藏设备"。然后在下面右边的窗口中点击"非即插即用设备"，找到"beep"，右键单击，选择"禁用"，虽有按提示操作，重启电脑即可。
