I have an old Toshiba Laptop (Satellite 1900-03) running Windows XP. I recently bought a little microphone to plug into the mic port but discovered that the sound is being fed live through the speakers causing feedback.

My question is how do I stop the 'live' microphone sound being piped instantly through the speakers without normal sound still being played?

I assume you mean that the microphone sound is being played back through the speakers constantly.

Try the following:

Go to the Control Panel, and click on Sounds and Audio Devices.
Under Device volume, click on Advanced.
Under Microphone, check the Mute button.

If the "Microphone" section is missing, go to Options -> Properties, and under the Playback section, enable it.

If you have Windows XP:

1. Open the Control Panel
2. Select Sounds and Audio Devices ⇨ Audio Tab
3. Go to Volume on Sound Recording
4. Select Advance under Microphone and check the Do not monitor check-box.

This way, you should be able to keep using the microphone without feedback from any speakers.

Update For Windows 10 or Windows 7 issue:

The tick from "Listen to this device" should be off. It implies, that Windows is making live monitoring of your commands, may be. You can still use your mic in applications and will not hear your mic in headphones/speakers.

The best suggestion seems to distance your mic from the speakers ...
