Fix microphone not working after Windows 10 1803/1809/1903 update

Starting with Windows 10 version 1803 (April 2018 update), Microsoft changed the behavior of microphone app access setting so that it affects desktop applications as well.


  • 9 Feb 2019: Updated the guide to include suggestion about turning on the microphone for Win32WebViewHost app
  • : Article published

To fix this do the following:

1. Go to Windows settings and select Privacy

2. Select Microphone and switch on the "Allow apps to access your microphone" toggle.

3. Under "Choose which apps can access your microphone" check that Win32WebViewHost (later renamed as Desktop App Web Viewer) is turned on as some desktop applications will need it.

4. Restart those applications where you've wanted to use the microphone.

5. (Optional) To block apps access to microphone you will have to toggle microphone off for each app. You will have to do this after each new app you install. It's recommended that you do not turn off microphone access for Win32WebViewHost (later renamed as Desktop App Web Viewer) as some desktop applications will need it.

Applies to Windows 10 versions 1803 (April 2018 update), version 1809 (October 2018 update), version 1903 (April 2019 update), version 1909 and later, Windows Server 2019.

Useful for Skype, TeamSpeak, Discord, WhatsApp, Steam voice chat, OBS Studio, XSplit, Bandicam, Adobe Audition, Audacity, ocenaudio, Edge, Chrome, Firefox, Opera, Facebook Messenger, Zoom etc.

Thanks to Shane and RatusNatus for the tips.

    Thanks for this guide.

    In my windows there are ONLY MS software to be allowed and Win32WebViewHost to everything else.
    This is the one to other apps like Steam and Discord...

    I want to add that even the Mic test In Windows settings will not work without the Win32WebViewHost process allowed.
    I don't know if this is new but I had to enable it to use the mic.

      Thank you for the info regarding Win32WebViewHost. It might be that the behavior has changed with later updates or I didn't tested properly when Win32WebViewHost was set to off. Will check and make the proper changes.

    I solved it by letting Cortana do it. He worked to get the voice recognized and inserted a new microphone that had previously disappeared. Now works. He's always very weak, but it works.

    This still did not work for me. I'm using Razer Thresher Ultimate wireless headset.
