With Windows 10, my computer does even acknowledge the existence of a video or audio track. They are there on my phone and I can view them on a friend's computer if I can borrow one, but they are no longer visible on my mine.

Prior to my upgrade from Windows 8.1 it was quite easy to view on my computer (a Dell laptop) the videos on my phone. I merely plugged the phone into the computer clicked on the phone icon that popped up on my screen and I viewed or dragged and dropped video and audio tracks to my desktop. No such luck now.

Is there a setting in Windows 10 that I can adjust so that it can "see" my videos and audio tracks?
