There are times when you absolutely need to mute your microphone immediately when you are in a voice call or video conference. However, there is no general hotkey in Windows 11 that allows user to mute the mic for the entire Windows (which affects all apps).
To be able to mute the microphone with a hotkey in Windows 11, we will need the help of a third party app. This guide will show you how to mute microphone with hotkey in Windows 11 using an app called MicMute. We will also show you common hotkeys to mute mic for several popular communication apps such as Discord, Zoom and Microsoft Teams.

Mute mic hotkey using MicMute
MicMute is a free and extremely simple app that allows users to mute the microphone for the entire Windows (which affects all apps as if you are temporarily disabling the mic) with a keyboard shortcut that you can set. You can quickly unmute the mic by pressing the same hotkey again.
This app was last updated in 2020, but it works perfectly on Windows 11. To quickly mute or unmute microphone with keyboard shortcut in Windows 11 using MicMute, follow the steps below.
1. Go to the following page to download MicMute and install it.
2. During the installation, the setup wizard will ask for permission to run on startup. This is optional but recommended because the app needs to be running in order for the hotkey to work. To save you hassle from having to launch the app every time you start your computer, you can allow the app run on Windows startup automatically.
3. Once installed, open the app settings by selecting the app from the taskbar corner.
4. In MicMute window, select Options > Setup shortcut.
5. From there, you can configure the keyboard shortcut (hotkey) to mute or unmute your mic. The default key is Left Ctrl + Left Alt. Make sure to use a shortcut that doesn’t clash with any hotkey in any of your apps or games.
6. After configuring the mute mic hotkey, try to press it. You will then see a notification pop up that tells you the mic is now off.
7. To unmute the microphone, simply press the same shortcut key again. The mic should then be turned on again.
If you don’t like to rely on any third party app, you can only mute your mic using hotkey that is assigned in the app that uses your microphone. Below is a list of hotkey to mute mic in some of the most popular communication apps in Windows 11.
