List of operating systems

In computer science , an operating system is a set of programs that directs the use of the capabilities of a computer by application software .

• Microsoft Windows (latest version: Windows 10): Microsoft’s operating systems are currently preinstalled on more than 91% of personal computers ^{[ref. necessary]} .
