Windows 10: Logitech C920 Webcam issues

So I have an odd issue.

My webcam had been working fine on my Windows 10 desktop computer until a month or two ago. Now when I plug it in it shows up under Imaging Devices on the device manager, however the webcam does not turn on when opened up in skype, discord, OBS etc. It seems like only skype and discord recognize it exists, however it looks like the mic picks up sound, but again no video. OBS doesn't even have the device as an option. I have uninstalled and reinstalled the drivers, etc and nothing.

The odd part is my Windows 7 laptop reads my webcam perfectly fine, so I know the webcam itself still works, but now it doesn't work on my Windows 10 desktop.

Would anyone possibly have suggestions or ideas of what might be going on?

Logitech c920 webcam no longer works.

I use a Logitech c920 webcam with my Dell 5567 laptop.

Setup is Windows 10 version 1709, latest.

After the latest Windows update, when I open the Logitech c920 software interface the webcam is not detected. But if I click on Quick Capture, I can see images but the webcam controls and advanced settings are no longer available. When I open up Preferences,
the microphone setting does not function.

I've already done a complete reinstall, several times, but to no avail.

If I use Skype and select the c920, again the imaging/video works. But also cannot open the c920 webcam settings from within Skype video settings.

Is there a fix for this?

just to add more spookiness, the Settings option in Skype shows that the C920 is being used:





..so it will run as an app from within Skype, but not as a stand-alone program via the Desktop Shortcut
- which is a bit odd..

I uninstalled the XBox App from the Start Screen, just in case the webcam was defaulting to that software,
- but no luck yet.. (??)

I've just noticed that the Windows Firewall includes an item called "Windows Camera"



- I wasn't aware that this even existed..
- is it possible that the Logitech Webcam software is defaulting to this location?
