Most people assume Linux is a rounding error on the desktop. The actual numbers tell a different story. We pulled the latest data from every major tracking source and laid it out with full context.
Linux desktop market share reached 4.7% globally in 2025, up 70% from 2.76% in 2022. The United States crossed 5% for the first time in June 2025. India reached 16.21%. On Steam, Linux gaming hit an all-time high of 3.2%. The growth is accelerating: it took a full decade to go from 1% to 2%, another 2.2 years to reach 3%, and only 0.7 years to go from 3% to 4%. Windows 10 support ended in October 2025, leaving an estimated 240 million PCs unable to run Windows 11. Those machines are not broken. They fail a single hardware check. Linux runs on all of them. Meanwhile, Linux already powers 100% of the world's top 500 supercomputers, roughly 59% of all websites, and nearly half of all cloud workloads. The desktop is the last tier where it has not taken over.
The Desktop Numbers
The primary tracking source for desktop operating system share is StatCounter, which measures web traffic across over 5 billion monthly page views. Their data shows Linux at approximately 4.7% of global desktop usage as of 2025. That puts it behind Windows (roughly 71%) and macOS (roughly 13%), but the gap with macOS has been narrowing.
The more interesting story is the acceleration. Linux spent nearly two decades getting from zero to 1% in 2011. The second percentage point took another full decade, reaching 2% in 2021. After that, the pace changed.

The shrinking time between milestones is the headline. Each percentage point is coming faster than the last. At the current pace, analysts project Linux could reach 6% globally by late 2026.
Regional numbers vary significantly. India leads major economies with 16.21% Linux desktop share as of July 2024, driven by cost sensitivity, a large developer community, and government digital literacy programs. The United States hit 5.03% in June 2025, crossing the 5% threshold for the first time. The U.S. Digital Analytics Program reported 6% of federal website visitors running Linux as of August 2025. Several European nations sit above the global average, pushed by government open source mandates.
Among developers specifically, the numbers are much higher. The Stack Overflow 2025 survey found that 27.8% use Ubuntu alone for personal use, with significant additional usage across Debian, Arch Linux, Fedora, and others. Developer adoption has historically been a leading indicator of broader adoption.
What Is Driving It
Windows 10 End of Life
Microsoft ended Windows 10 support on October 14, 2025. After that date, no more security updates, no more patches, no more technical support. Machines running Windows 10 still work, but they accumulate vulnerability exposure over time.
The problem is that many of those machines cannot upgrade to Windows 11. The requirement for TPM 2.0 (a hardware security chip) disqualifies a significant portion of the installed base. Canalys estimated that approximately 240 million PCs worldwide cannot make the upgrade. That is roughly 20% of the global Windows installed base. US PIRG estimated the transition could generate over 700 million kilograms of electronic waste.
Microsoft offers Extended Security Updates at $61 per device per year for enterprises. The price doubles each consecutive year: $122 in year two, $244 in year three. For consumers, a limited extension was eventually made available, but only for one additional year.
The math: 240 million functional computers, unable to run the latest Windows, facing end of security support. Linux distributions like Ubuntu, Mint, Fedora, and MX Linux run on all of them. For free. With ongoing security updates. The machines do not need to be replaced. They need a different operating system.
We covered this in detail in our earlier post on keeping old computers running with Linux. The Windows 10 end of life made that guide significantly more relevant.
The Steam Deck Effect
Valve's Steam Deck, a handheld gaming device released in 2022, runs SteamOS, which is based on Arch Linux. It was a commercial success. More importantly, it proved to millions of gamers that Linux can run games.
Steam's monthly hardware survey showed Linux usage reaching an all-time high of 3.2% in December 2025. That is a tripling of Linux gaming market share over the past decade. Valve's Proton compatibility layer, which translates Windows game calls to Linux, now supports the vast majority of the Steam library. Gaming-focused distributions like CachyOS and Bazzite have shown consistent month-over-month growth as a result.
Gaming was the last major argument against Linux for consumer use. That argument has weakened considerably. Some anti-cheat systems still block Linux, and a handful of titles require workarounds, but the gap is smaller than it has ever been.
Government Adoption in Europe
Several European governments have moved to Linux and open source software at institutional scale.
Germany's state of Schleswig-Holstein became the first European region to fully replace Microsoft tools with Linux and LibreOffice across all public offices, completing the transition in April 2024. France operates over 103,000 computers running GendBuntu, a custom Ubuntu-based distribution built for the national gendarmerie. Denmark's Ministry of Digital Affairs announced a transition from Microsoft to open source platforms between June and November 2025. Switzerland committed $231 million to building a national cloud service and passed legislation requiring all government-developed software to be released as open source.
The European Union has discussed the possibility of an "EU-Linux" operating system for public administrations across all member states. Whether that materializes remains to be seen, but the direction of travel is clear: multiple governments are actively reducing their dependency on proprietary software.
Where Linux Already Runs
The desktop number only tells part of the story. The 4.7% figure measures personal computers running web browsers. It does not capture servers, cloud infrastructure, embedded systems, or supercomputers. When you expand the view, the picture changes considerably.
Every one of the world's 500 fastest supercomputers runs Linux. That has been the case since November 2017. Roughly 59% of all websites with an identifiable operating system run on Linux. Nearly half of all cloud workloads globally run on Linux. Your phone, if it runs Android, is running the Linux kernel.
Most of the internet infrastructure you used today to reach this page runs on Linux. The desktop is the one area where it has not achieved the same penetration, and that is the area where the growth is now accelerating.
What the Numbers Do Not Tell You
Desktop Linux is at 4.7%. Windows is at 71%. That gap is real and it would be dishonest to pretend otherwise.
Application compatibility has improved substantially, but gaps remain. Adobe Creative Suite has no native Linux version. Microsoft Office requires either the web version, LibreOffice as an alternative, or a compatibility layer like Wine. Most professional software in video editing, music production, and CAD has Linux options, but they are not always the industry-standard tools that employers require.
Gaming works well through Valve's Proton compatibility layer, but some online games with anti-cheat software still block Linux users. This is a policy choice by the game developers, not a technical limitation, but the result is the same: certain popular titles do not work.
Enterprise adoption on the desktop lags behind server and cloud deployment. IT departments standardize on what they know and what their existing software stack requires. Migrating an organization's desktops involves retraining, software auditing, and support infrastructure changes that many IT teams are not ready to undertake.
Driver support has improved significantly, especially for AMD hardware. NVIDIA support has historically been more difficult, though NVIDIA's open source kernel module release in 2024 improved the situation. Newer laptops with hybrid graphics or specialized hardware can still present configuration challenges.
The 4.7% figure also likely undercounts real usage. StatCounter measures web traffic from browsers, which misses Linux servers, embedded systems, IoT devices, and users behind corporate VPNs or air-gapped networks. The actual number of machines running Linux is far higher than the desktop share suggests.
The E-Waste Connection
240 million PCs. Over 700 million kilograms of estimated electronic waste. That is what the Windows 10 end of life represents in physical terms.
These machines are not broken. They run browsers, email, office software, and video calls without issue. They fail one hardware check: a TPM 2.0 requirement that most users will never interact with directly. Microsoft's position is that TPM 2.0 is necessary for security. Critics point out that the same machines ran Windows 10 securely for years without it.
Linux distributions run on hardware going back 15 years or more. MX Linux, the distribution this blog was originally built on, is specifically designed for older and lower-powered hardware. Linux Mint, Ubuntu, and Fedora all run comfortably on machines from the early 2010s. The computer someone was about to recycle might have another five years of useful life with a different operating system.
We covered the hardware angle in detail in Your Old Computer Is Not Broken. Windows Is Just Done With It. and the practical steps for running both systems in Installing Linux Without Removing Windows. The Windows 10 deadline has made both of those guides more relevant than when we originally published them.
What We Run
This blog is branded "Hand-coded on MX Linux" because that is where it started. The workstation has since moved to Nobara Linux 43, a Fedora-based distribution optimized for gaming and creative workloads, running KDE Plasma 6. All of our client websites, server infrastructure, development environments, and daily work run on this machine. It is not a side project or a hobby setup. It is the production environment for the entire business.
Linux already runs most of the internet, the world's fastest computers, and most of the cloud. Desktop adoption is the last tier, and it is growing rapidly.
