Global market share held by computer operating systems 2012-2025, by month
Published by
Microsoft’s Windows is the most widely used computer operating system in the world, accounting for 69 percent share of the desktop, tablet, and console OS market in March 2025. Apple’s macOS ranks as the next most widely used operating system, while its iOS mobile operating system, the standard installation on all iPad devices, ranks fourth. Linux OS versions serve as the primary option for users who prefer open-source software and intend to avoid the influence of major OS developers.
Operating Systems
Operating systems serve as the underlying platforms which connect computer hardware and software. They provide users with the graphical interface through which they issue commands and perform tasks on electronic devices. Billions of people make use of these devices and their operating systems on a regular basis, meaning that the companies that develop these widely used technologies have a great deal of influence on the daily lives of internet users around the world. Although Microsoft Windows is the clear leader in terms of desktop operating systems, the company’s mobile device operating system failed to make a successful transition into the smartphone market, where Android and iOS are essentially the only two options.
