Windows operating systems market share of desktop PCs worldwide 2017-2020

Windows 10 is the most popular Windows desktop operating system, accounting for over 75 percent of the market share as of December 2020. As the leading Windows version before the introduction of Windows 10, Windows 7 continues to enjoy a significant amount of the Windows desktop operating system market with 18.03 percent as of then.

A global dominance in computer operating systems

  Microsoft’s Windows is the most widely used computer (desktop, tablet and console) operating system (OS) in the world with over 70 percent of the market share as of 2020. Their closest competitors - Apple's macOS and iOS - only hold a combined 20 percent of the market. Despite its dominance in the computer OS market, Microsoft has been unable to have the same impact on the mobile OS market, where Google’s Android and Apple’s iOS split the market with a combined share of close to 99 percent.

Operating systems

   Operating systems are the underlying platforms connecting computer hardware and software. They provide users with the graphical interface that enables them to issue commands and perform tasks on electronic devices. Almost every device today- from smartphones and desktop computers, to graphical calculators - requires an operating system to function.
