Hi Bill,
I can understand how frustrating this must be, especially after you’ve already worked through several suggested fixes and Win + H still shows Listening without picking up your speech.
Windows 10 has reached end of support (EOS), but you can still try the troubleshooting steps below to see if they help.
First, try reinstalling the microphone/audio driver. Open Device Manager, expand Audio inputs and outputs and Sound, video and game controllers, uninstall the relevant microphone/audio device, then restart the PC. Windows should attempt to reinstall the device automatically.
If there’s no change, open Command Prompt as administrator and run these commands one at a time:
DISM.exe /Online /Cleanup-image /Restorehealth
sfc /scannow
Let each command finish completely, restart the PC and then test Win + H again.
If the microphone works normally elsewhere but dictation still doesn’t, you could also try a clean boot. This can help determine whether a background program or service is interfering with dictation. Remember to return Windows to normal startup afterward.
*Disclaimer: A "clean boot" starts Windows with a minimal set of drivers and startup programs. It helps to determine whether a background service is interfering with your game or program and to isolate the cause of a problem.
These steps of "clean boot" might look complicated at first glance. However, to avoid any trouble for you, please follow them in order and step-by-step so that it will help you get back on track.
Could you also press Win + R, type winver and let me know the Windows version and OS build shown? And is this a personal PC or one managed by a work or school organization? Those details may help narrow this down further.
I hope one of these additional steps helps get dictation responding again.
