Possibly he did part of it, but by that time he had a company (Microsoft) with many programers.
Gary Kildall was the first person to create an operating system for the computers which was separate from the hardware. He was a PhD in computers and he named his system CP/M. The first versions of Windows were based on a system which was invented or designed by Tim Paterson. He named his system QDOS. Microsoft, a company founded by Bill Gates and his school friend Paul Allen in 1975 improved on it. It is a myth that Bill Gates invented Windows. He only founded the company which designed a more user friendly computer operating system called 'Windows' It is said that there was an oral agreement between the IBM (one of world leading companies in computers) and Gary Kildall but G. Kildall never benefited much, monetarily, from his invention. He died in 1996 and never got the credit he deserved for his invention.
