With appologies to all MS engineers… 
There were three engineers in a car; an electrical engineer, a chemical engineer, and a Microsoft engineer.
Suddenly, the car stops running and they pull off to the side of the road wondering what could be wrong.
The electrical engineer suggests inspecting the electronics of the car and trying to trace where a fault may have occurred.
The chemical engineer suggests that it may be an issue related to the fuel, and that it may be getting blocked somewhere.
The Microsoft engineer, not knowing much about anything, says, “Why don’t we close all the windows, get out, get back in, open all the windows and see if it works?”
