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 stripping down the electronics of the car and trying to trace where a fault may have occurred.
The chemical engineer, not knowing much about cars, suggests maybe the fuel is becoming emulsified and getting blocked somewhere.
The Microsoft engineer, not knowing much about anything, came up with a suggestion. "Why don't we close all the windows, get out, get back in, and open all the windows and see if it works?"
