Bill Gates co-founded Microsoft, a company that has profoundly shaped the computing landscape. 

He is a pivotal figure who democratized computing by heralding a revolution in bringing Personal Computers (PCs) to every home on Earth.

He famously dropped out of college and created the operating system (MS-DOS), followed by a user-friendly Windows Operating system. Windows captured the imagination of the corporate world, which quickly adopted the use of Windows PCs. The dominance of Windows in the corporate world remains virtually unchallenged even today.
