Microphone won't turn off

[Guest]

My microphone is on and I can not find where to turn it off at. I keep hearin
it through my speakers and I can't listen to anything else. Help

Unplug it !

Right-click the speaker icon in the taskbar and select Recording Devices.
In the properties page that pops up, Double-click the microphone. Another
page will open; click the Levels tab. Here you'll find a little button to
the left of the Balance button. Click it once to mute the microphone.

Or, as Bill suggests, simply unplug it.
