L470 webcam and biometric login not working after Windows 10 Pro 1903 update

After updating Windows 10 Pro to version 1903, my webcam shuts off after 1 second and biometrics for Windows login is no longer an option.

I tried deleting the driver for the webcam and afterwards manually installing the latest driver from Lenovo - no change.

 

ThinkPad L470

- Serial: ********

- Product number: 20J4002DMX

- BIOS-version: R0GET70W 1.70

 

Moderator note: serial number removed to prevent abuse.

Can you run "View All Problem Reports" (just type this into the start menu) and see if there is any log corresponding to the time when you start the camera and it shuts off after 1 second?  It sounds like something is crashing so I think there should be some kind of log about it.

There are several reports of svchost.exe crashing (it's in Danish, but I hope you get the jist):

Based on your information, it seems that RsProvider.dll is crashing.  I have heard this kind of problem before, but I am not sure why it happens.  Please check the following article if the information about EnableFrameServerMode can solve your problem.

Great!

I wanted to mark that as the solution, because it solved the webcam part of my problem.

 

However the biometric login is still not an option in this version of Windows. Any thoughts on that part?

Sorry, I have not heard this problem before.  Do you mean logging in with face recognition, or fingerprint, or something else?  When you say it doesn't work, do you mean that you can't add the sign-in option in Windows settings?

 

Windows keeps logs in Event Viewer -> Applications and Services Logs -> Microsoft -> Windows -> Biometrics -> Operational.  I don't always know what these logs mean but maybe there is something suspicious there?

The option to use fingerprint for login is no longer available - now I'm only able to use Pin or Password. I haven't tried adding it, as it has disappeared after the Windows Update. Where would I be able to add the option again?

Windows keeps logs in Event Viewer -> Applications and Services Logs -> Microsoft -> Windows -> Biometrics -> Operational.  I don't always know what these logs mean but maybe there is something suspicious there?

I've just taken a look - The earliest log is from September 26, which might be coincident with the update:

 

"Tjenesten Windows Biometri kunne ikke starte sin sikre komponent.

Handlingen mislykkedes med følgende fejl: 0x80070032."

 

Again in Danish, but it says something in the lines of:

"The service Windows Biometry couldn't start it's secure component.

Action failed with the following error: 0x80070032."

 

There are a bunch of different logs.

There seems to be three different errors or so connected to each timestamp.

Is there any device in Device Manager -> Biometric Devices?  Is there any unusual status or error shown there?

Well it seems as if the driver for the fingerprint sensor is not working.

 

Something in the lines of:

"This unit is not working properly, because Windows cannot load the drivers for the unit. (Code 31)

{Action failed}

The requested action failed."
