Can you help with microphone mute on/off button not working on Windows 10?

How is it working now?

Same as before  -- the microphone button doesn't work while the headset and sound via the microphone are flowing as before -- my apologies -- I should have mentioned this in my earlier post.  Just for fun I also rebooted and tested again to be sure all the refreshes of device drivers/hardware scan and services start steps were fully applied.  I confirmed the Windows Audio services are automatically started.

I additionally have tried adding the privacy settings and sound settings as shown below with the same results. 

I'm wondering how does pushing the mic hardware mute button get transferred to Windows 10 via Bluetooth?   There's not an overall "mute" microphone capability in any of the screens so far.   For example, I can mute audio (headphones/speaker output) from the task bar sound icon, but mute microphone might be app specific? -- see bottom screenshot.  I cannot see a mute capability until after I launch each app/ join meeting.

Here is what the audio settings show

How is it working now?

Thanks, uninstalled and re-installed device via scan for hardware changes which re-installed both instances of Hands-Free below

Restarted Services.msc Windows Audio, looked also to restart endpoint, but it prompted that windows audio would restart -- did so anyway so audio service restarted at least twice

You can type Services.msc in Search box, open Services panel as Admin. Check that the Services listed are running.

Be sure to renew the prompt which asks What Device was just plugged in, as this can be the key.

Thanks Greg, I found the path as you described -- it looked like I got to the same place a different way, but just in case I ran the troubleshooter and the detailed results reflecting no issues are below. I've surfed to the second link in the list, and it looks like the steps include updating/re-installing drivers -- there aren't any new drivers.   Some additional background,  I didn't mention earlier -- the headset is new and the laptop is also new with the latest updates applied -- audio over Bluetooth was just installed and I can hear and talk.  So rolling back to earlier versions won't apply here since it never worked before.    The mute button is the challenge.   Based on the website info and that the drivers are fresh and up to date-- should I go through a driver uninstall/reinstall process again?
