Windows 10: Webcams Issues

I own a Razer Blade (Early 2016, i7-6th gen, GTX 970M), and I have a very peculiar issue. For whatever reason, my webcam will not work. It takes the Generic USB Webcam drivers that Windows uses, but any time you use it, it only shows a black screen, or attempts to load. I sent it out to get it repaired, and after having it sent back and wiped, it still didn't work. I wiped it myself, and it worked just fine. After reinstalling my backup image of my OS, the issue returned. Currently, I can't reset it again (my image apparently has a corrupted recovery partition...) and am trying to figure out what could be causing the webcam issues. Are there any tools to diagnose software/operating system related issues with webcams? Would it just be easier to grab a Windows 10 ISO and reflash it again and reinstall? Thanks in advance.

How to change default webcam in windows 10

So there any updates to this. I can confirm that this still is an issue for me and that disabling the internal Webcam does not set an external Webcam as default. If you cannot select a Webcam in an application then you will have no Webcam after disabling
the default internal webcam

 

webcam issue

I have resolved the problem I was having with my wireless mouse thanks to the community, after my laptop was updated. Now I seem to have another issue

my usb connected Logitec C-615 has suddenly stopped working. The computer recognizes that it is installed, the actual logitec software app, says not detected.

The windows 10 camera app recognizes it and was able to take pictures with it. but websites suddenly are not showing it as connected either.

any suggestions?
