That’s it you have successfully Fix Webcam not working after Windows 10 Anniversary Update but if you still have any queries regarding this post then feel free to ask them in the comment’s section.
I followed all the steps in Method 1 and it didn’t work. I also uninstalled and reinstalled my Logitech C-920 webcam countless times.
I even tried to go back to the previous build as you suggest in Method 2, but Windows was not able to proceed.
It’s a huge problem. My webcam won’t turn on.
I tried the troubleshooting section and it says that it’s related to USB 2.0 vs USB 3.0: “USB composite is anterior USB and it can’t work on USB 3.0.
However it worked last week no problem.
Can you help in any way?
what I did was uninstall my drivers and let it run off the generic windows drivers
you will probably get an update for the webcam which you should then uninstall drivers again after the update
Can you confirm that for method 1 (registry fix), step 7, the value of EnableFrameServerMode has to be set to 1 (as in your text) and not 0 (as on the picture) ?
