Who Invented Windows?

Bill Gates and Paul Allen invented Microsoft Windows in 1983, and Windows 1.0 was ready for use by 1985. It was named "Windows" because the user was able to change between screens, similar to how would look out a different window.

Windows 2.0 came out in 1987 with improved graphics support and more memory. The first Windows that had a Start button and built-in Internet support came out in 1995. Updated versions continued to be produced, including Windows NT, Windows 95, Windows XP, Windows 2000, Windows Vista and Windows 7. Windows 8.1 came out in 2013, and Windows 10 is set to be released some time in 2015.
