If I uninstall the microphone from my laptop, can no one hear me anymore?
You can't uninstall a microphone because it is hardware. You can deactivate it in Device Manager, then nobody will hear you.
That's why people don't automatically become deaf.
If you know what you are doing, you can unscrew the laptop and remove the microphone.
You can only uninstall the drivers yourself or mute the microphones.
Uninstalling is not possible.
If you don't want the microphone, a specialist in the laptop should probably remove it, but that would be subject to a charge and the warranty will be voided.
