My Idea For Best Patented Invention

I think surely one of the best inventions of the last century must be the Windows operating system. For example who knows how long it would have taken for a company to invent and make so user friendly had not Mr Gates's Microsoft not come up with the idea of such a elegant user friendly graphic interface for we humans to interact with ourr appliance.

Let's think about itt for a moment, without Windows there would be no Microsoft Office, no, Internet Explorer browser or any of the Windows platform software we can employ and enjoy in this early 21st Centurry.
