Windows is a series of operating systems developed by Microsoft Corporation. An operating system is the fundamental software that manages computer hardware and provides services for computer programs. Windows allows users to interact with their computers through a graphical user interface, run applications, manage files, connect to the internet, and perform virtually any computing task. Since its introduction in 1985, Windows has become the most widely used desktop operating system in the world.
