Microsoft tests say this Dell laptop should work with Windows 10 (64 bit) & I've resolved most issues now. Two remaining ones are 1) semi-fixed namely the monitor driver that it was trying to make a Generic PnP driver which was terrible. I've set it to one of the few other options ie flat panel 2048 x 1024 at 60hz is that best? I can't find any update on the site that fixes this.
The bigger issue is with the inbuilt microphone that comes as part of the webcam, it worked fine on W7 but while it works, the pick up is way, way to low and cranking up all the volume options has no useful impact. Again I've looked up any new drivers on the site but another blank.
I tried the diagnostic software on the support site but whether simple and generic or specific to the microphone issue it goes as follows: installs the Dell software, goes into the test phase from which it never emerges, some dead loop even after hours.
Any ideas out there?
