In recent years, Microsoft Windows' dominance in the world of personal computing has begun to show worrying cracks. The company has announced that its operating system has lost 400 million active users or devices since 2022., a figure that represents almost a third of its installed base in just three years. According to the latest official data, Windows currently has around 1.000 billion active devices, well below the record reached just three years ago.
This decline has not happened overnight, but It is the result of a combination of factors that affect both home and professional users.Windows computers, which for decades were the epicenter of computing, are losing ground in a market where mobile phones and tablets are becoming increasingly capable and ubiquitous. Many people today prefer to use their smartphones for tasks that were previously only possible on a PC, from managing documents to consuming entertainment.
The domino effect of Windows 11 and the stagnation of the sector
One of the triggers for this massive loss of users has been the launch and reception of Windows 11. The new operating system has been surrounded by controversy and dissatisfaction among users., citing stability issues, restrictive hardware requirements —such as the mandatory use of the TPM 2.0 chip—and a user experience that's less than convincing. Furthermore, unpopular new features like the integration of ads into the system itself and the perception that improvements are limited have further slowed migration.
53% of desktop users remain loyal to Windows 10, despite the fact that its official support will end in October 2025. Many computers, even in perfect condition, have been left out of the update to Windows 11 due to technical issues, forcing an uncomfortable decision: renew the hardware, continue using an obsolete version—with all the risks that this entails—or explore alternatives such as Linux or macOS.
The situation worsens as other platforms gain ground. Apple, with its Macs equipped with ARM chips, is making progress especially in professional environments., while ChromeOS is growing in the education sector and Linux is increasing its share in the public sector and among European companies concerned about technology dependency and licensing costs. Countries such as Germany, Denmark, and France have begun to abandon Windows in their administrations, opting for open source software.
Microsoft's external threat and internal challenges
At the same time, the world of video games, a traditional Windows stronghold, is beginning to show signs of change in the face of the SteamOS pressure, Valve's Linux-based operating system, which is a success on portable consoles and also aims to conquer traditional desktops.
Meanwhile, Microsoft's attempts to revive the market have had little impact. The new artificial intelligence features in the so-called PC Copilot+ They have not generated the expected enthusiasm among consumers, and many users continue to express their discontent on social networks and forums like Reddit, where they criticize the company's strategy and lack of real innovation.
By 2025, figures show that Windows 11 barely reached 36% of the market, while Windows 10 remained at around 60%. Recent statistics from StatCounter confirm that, just a few months before the end of Windows 10 support, more than 500 million computers are still relying on this version. It's unlikely that millions of users will switch devices all at once, so the fragmentation of the user base is expected to become even more acute.
An uncertain future for Windows
Microsoft is aware of the seriousness of the situation and is considering accelerating the development and launch of Windows 12 to try to reverse the trend. However, direct competition from alternative operating systems and the unstoppable advance of mobile devices and the cloud mean that Windows' historical hegemony is being challenged like never before.
The next digital desktop makeover will depend on a key decision of millions of users: upgrade hardware to remain in the Windows ecosystem, resist change and take risks, or simply look for a more flexible and modern alternative. The loss of 400 million users in just a few years clearly reflects that the era of absolute Windows dominance is coming to an end, and that Microsoft will have to reinvent its strategy if it wants to once again set the standard in personal computing.
