Thinkpad L460 webcam issues on Windows 10
Some colleagues reported flickering webcam issues on their L460 computers. The camera turns on for a couple of seconds and then stops working. With all this remote work it's really annoying.
The fix is really simple, just rename the RSProviders folder in C:\Program Files\Realtek. See here for more details: https://www.winhelponline.com/blog/webcam-anniversary-update-windows-10-yuys-standard/
I suspect this applies to L450 and L470 models too.
