Why I can't connect my Lumia 920 to windows 10 PC.

[WPCentral Question]

I recently upgraded window 7 to 10. Now this PC doesn't recognizance my phone Lumia 920 in USB connection. I couldn't use 'Project my screen' app as well. Does any have any idea to solve this issue?

Is it not seeing anything when you plug it in? Or does it see an "unknown device"?
