With an aggressive management style and strong understanding of the tech landscape, Gates was able to turn Microsoft from a fledgling start-up into one of the largest companies in the world, putting a Windows-powered PC on nearly every desk -- and getting his company inducted into the Dow Jones Industrial Average (DJINDICES:^DJI).
