I am trying to get a USB webcam to work for our CIO's laptop. The webcam was previously working but now isn't.
The webcam should work just with the generic Microsoft drivers, and it does on my machine. Both machines are pretty freshly deployed. The issue with the non-working laptop is that the generic, Microsoft provided drivers are failing a signature validation, which shouldn't happen with these built-in generic drivers. The exact same drivers are working fine on another laptop. The vendor does not provide Windows 11 drivers, but the generic MS drivers should work fine.
To try to repair what I believe to be corrupted drivers, I have attempted "DISM.exe /Online /Cleanup-image /Restorehealth" and "sfc /scannow" and neither resolved the issue (and they never have in my experience 🙂). I would try to delete the drivers, but the normal way of doing so isn't an option since they are generic drivers, and I'm not sure of the consequences of trying to replace built-in drivers with those from my working machine on the same build of Windows.
I am looking for guidance on how to repair these generic drivers.

Whoops, I forgot that I used a pastebin.
The model is Logitech C270, but this is irrelevant to the generic MS driver failing it's signature check.
I don't know how many times I should need to say that the problem is with the generic driver, a component of the OS, failing its signature check.
Hi Brendan,
If the device that the webcam is working on is on the same build No. as the device the webcam will not work on, then yes, you should try copying over those drivers, that would not have any consequences, it will either solve the problem or it won't and doing that will certainly not cause any further problem.
Hi Brendan
What is the Make and exact Model No. of that external webcam?
Did you attach a redacted version of System Info?
Hello, attached is a redacted export from msinfo.
The camera app will use the integrated camera on the laptop. As I said before, the generic Microsoft driver is somehow failing its signature check, and so the external USB webcam does not initialize, it therefore doesn't present itself in any app that uses cameras.
Hi Brendan
I am Dave, I will help you with this.

I need some more information about the laptop, click the Start Button, then just type msinfo and press Enter
Please provide a screenshot of the resulting System Information window.

Open the Camera App, what is the exact error that appears there and is there a camera icon on that screen, what does that look like, does it have a line through the camera?
