The dominance of Windows is not a fate set in stone. In June 2019, Microsoft’s system still crushes the competition on computers, with over 77% market share, but elsewhere, the lines are shifting: Android reigns on mobile, iOS imposes itself in some areas, while Linux and macOS maintain their strongholds. Beneath these numbers, strategies clash, uses are reinvented, and the balance of power hangs by a thread.
Overview of Operating System Market Shares in June 2019
At the beginning of summer 2019, the global map of operating systems draws clear boundaries. Windows maintains a spectacular lead on personal computers: more than three-quarters of machines run under its banner. This success is supported by an immense variety of models, flawless compatibility with professional software, and usage habits that span generations.

On its side, macOS is carving its own path. It does not invite itself everywhere, but it imposes itself in creative studios, among freelancers, in circles where the coherence of the Apple ecosystem is paramount. The upcoming release of Catalina promises to enhance this appeal, but the platform still does not reach the threshold of 15% of the global market, marking a targeted but limited success.
As for Linux, it stands as a discreet outsider. Less than 2% of personal computers use it, yet it has carved out a prominent place in servers, education, or administration. Its many variants, many of which are derived from Debian, attract users with their customization and security, even if the general public adopts it sparingly.

A comparison of operating systems in 2019 sheds light on these contrasts: on mobile, Android crushes the competition, while iOS finds its niche in developed countries. This duel shapes the digital environment of millions of people and guides the decisions of both publishers and experienced users.
Why Do Some Systems Dominate the Digital Landscape?
In 2019, the market for operating systems revolves around a few giants, driven by solid economic logics and strategic technical choices. The larger the user community grows, the richer the catalog of available software becomes, further strengthening the position of the dominant system. This is why Windows on computers, and Android on smartphones, hold the upper hand; the spiral is difficult to reverse.
Companies primarily seek stability and simplified management of their equipment. Individuals, on the other hand, want simplicity, a wide choice of applications, and a seamless experience. Systems that meet these expectations gain the advantage, as they offer security, reliability, and user comfort. Serving both as a technical foundation and a gateway to thousands of services, the operating system shapes the digital daily life.
Key Adoption Factors
Here are the criteria that weigh most heavily when choosing a platform:
- Software Compatibility: being able to install a wide variety of applications remains a key asset.
- Security and Updates: responsiveness to vulnerabilities reassures both professionals and individuals.
- Flexibility: some, like Linux and its distributions, attract users with their adaptability, even if their usage remains marginal.
The choice of an operating system thus goes beyond mere routine. It reflects a compromise between technological advances, industrial policies, and the concrete expectations of users. Since 2019, competition remains fierce: each new development can reshuffle the cards and disrupt the established balance.

Significant Developments and Trends Observed Since 2019
In just a few years, the market for operating systems has seen its innovation pace accelerate and its uses diversify. Leaders are reinventing themselves: increased security, cloud integration, modularity, mobility… The offering is expanding, driven by the need to access data anywhere and on all devices, in sometimes hybrid environments.
The arrival of macOS Catalina marked a milestone for professionals: stability, better interoperability, and new uses. On the Linux side, Debian-based distributions are slowly but surely advancing in servers, laboratories, and schools. Their strength: unmatched flexibility, a capacity to adapt to very specific needs.
Main Notable Changes
Three changes stand out clearly:
- Strengthening of Automatic Updates: system security is advancing rapidly.
- Growing Cross-Platform Formats: developers are gradually breaking down traditional barriers between systems.
- Rise of the Cloud: access to local resources and data management are evolving with the widespread adoption of hybrid solutions.
Market share analysis shows that positions remain generally stable, but the real battle is now fought in the realm of user experience and innovation. Technologies are intersecting, systems are enriching, and individual choices are gradually shaping the face of our digital future.
