Windows oh so popular

I had a doubt suddenly... Did Microsoft make the name "Windows" more popular by using it as the name of their product? Such a common household name, it has reached such a state, where in if my mom asks me open a window, my hand automatically goes to "Windows key + E". No matter, who, what anyone says, Microsoft has done an amazing job in popularizing their software on to a lotta desktops in the world!!

Which are people more aware of? If someone suddenly says "Close the window" or "Open the window", do you automatically think of the physical, real Windows or the ethereal, virtual software  - the Operating System by Microsoft? Lemme know as a comment ;-)!
