We couldn't find a camera compatible with Windows Hello Face

Hi MM RAHMAN,

Thank you for reaching out Microsoft Community. We apologize for the inconvenience this may have caused.

By the way, did the issue happen after installing updates on your Surface device?  This seems like a common issue since I had assisted 2 Community members who have the same problem with Windows Hello. 

To initially troubleshoot this issue, I would like you to follow the following steps below.

Check UEFI Settings if Cameras are disabled

 Press & hold the Shift Key and select "Restart" from the power options. Once "choose an option" screen appears, select Troubleshoot > Advance Options and UEFI/Firmware Settings > Restart > Choose Devices > Make sure the cameras are being enabled. Then, select Exit to restart your Surface.

If no changes after enabling cameras, to further troubleshoot the issue, please download thisin-place upgrade. Downloading the tool will re-install missing drivers and repair those that are corrupted . It won't delete files nor remove the applications you already installed. Just click the "Download Tool Now", run and install and click Next once you see "Upgrade This PC".

If this helps, please let our Community know by marking this post as an answer. Otherwise, don't hesitate to respond to this thread for further assistance.

Kind Regards,

After many attempts, I did the following to make it work:

Step 1:  Either uninstall any anti-virus or restore them to default.  I use ESET and just did a restore to default.  Important to do this first.

Step 2: Do the above Windows in-place upgrade, as described by MM Rahman.

Step 3:  Do the above Shift - Restart process.  First, disable the cameras.  Then restart the Surface.  Do Shift - restart process again, enable the cameras.  Restart the surface.

Step 4:  Start Device Manager and uninstall the camera.

Step 5:  Reinstall the camera, and update driver.  Search for updates on Windows  It will prompt you for a general Windows update - run that.

Step 6:  Do this, Procedure 4.  Don't bother with the others they won't work.

Procedure 4 :

1. Click on the Start button, type "run" and click on "Run"
2. Type "services.msc" (without quotes) and click on "Ok"
3. Find "Windows Biometric Service", double click on it and click on "Stop"
4. With File Explorer go to C:\Windows\System32\WinBioDatabase and make a backup of all the files just in case. Move that backup outside of that folder.
5. Once backed up delete all the files in C:\Windows\System32\WinBioDatabase
6. Open another time "services.msc", double-click on Windows Biometric Service and restart it.

I had to delete the WinBioDatabase twice.

Then I was good to go.

It depends on the Microsoft Surface device. While likely software related (the camera issue cropped up after a Windows update), I could not find online a biometric driver update or other fix. My Surface GO tablet was still on warranty so I was able to send it back to Microsoft. The replacement (which may have been my original tablet but re-imaged) arrived with an operating system and drivers that again support Windows Hello and its very handy face recognition feature.

HI ALL MICROSOFT AGENTS THERE!
