My webcam was working at some point. Most of the time it is connected to a dock and I hardly use it. Yesterday I have an important Skype call and  guess what :) I get the dreaded  0xA00F4244 error. 

Checking the device manager I discover that the integrated cam is nowhere to be found: 

I updated all drivers, performed a diagnostics and performed 2 fresh installations of windows 10 and nothing has fixed this issue. So I rush out and buy a standalone USB cam so I can be ready to do this call. Get home and connect the camera and it registers. I open the camera app and I have a still image of me. No video. I click the photo button in the app and get a new error: 0xA00F4292

If I launch Skype it sees the USB cam but only shows a black screen. It now also shows up in Device Manager: 

There are no updates available for the driver and I have tried uninstalling it and rebooting, but no different results are achieved. If I go here:

The USB cam works correctly - Very strange... So I really believe that it is definitely a driver/software related. On the other hand, where is my integrated cam? I also installed all chipset drivers from Dell hoping this would find it. At this point, I have nothing.. I see from Google, that there are tons of people with similar results, yet the "working" solutions for these individuals do not work for me. 

When I run diagnostics test from SupportAssist, I get no errors and everything is working fine. If I try and do a cam test, it reports that no cam can be found... I can see it on the bottom left corner of the laptop, so it's definitely there... 

Any tips or does anyone else have a solution that I might try?
