France will replace Windows with Linux in an ambitious software migration program on computers throughout the country’s public administration. The approved directive is one of the biggest drives in Europe to recover digital sovereignty against American technology companies.
Taking into account France’s influence in the European Union, the measure can (should) be a example to follow for other countries on the continenta turning point to reduce the digital dependence of the United States and a commitment in favor of open source software, technological control and digital data throughout the continent. The approved initiative not only contemplates changes in operating systems, but also in collaboration tools, cloud infrastructure and artificial intelligence platforms developed in Europe.
France will replace Windows with Linux and other software
The National Information Systems Security Agency and the General Directorate of Public Procurement of the State of France (DINUM), has approved a directive that contemplates relevant changes to advance digital sovereignty. The agency itself, which employs about 250 agents, will immediately migrate its workstations from Windows to Linux. All other French ministries, including their operators and affiliated bodies, will have to draw up their own plans by autumn 2026.
These plans must address eight categories: workstations and operating systems; collaboration and communication tools; antivirus and security software; artificial intelligence and algorithms; databases and storage; virtualization and cloud infrastructure, and network and telecommunications equipment.
David Amiel, the French Minister of Public Action, has motivated the initiative: «The State can no longer limit itself to recognizing its dependence; must be released. We must reduce our dependence on American tools and regain control of our digital destiny. We can no longer accept that our data, our infrastructure and our strategic decisions depend on solutions whose rules, prices, evolution and risks we do not control. The transition is underway: our ministries, operators and industrial partners are embarking on an unprecedented initiative to identify our dependencies and strengthen our digital sovereignty. Digital sovereignty is not optional ».
No specific Linux distribution has been mentioned in the public announcement, and each ministry retains the flexibility to choose its own migration path within that framework. The software replacement strategy It also includes other types of software, such as office suites. For the most common desk tasks, the agency has already released The Digital Suitea set of sovereign productivity tools developed and maintained by DINUM. The suite includes Tchap, an end-to-end encrypted messaging application already used by more than 600,000 public officials; Visio for video conferencing; an own webmail service; file storage and collaborative document editing.
The entire platform is hosted on servers from Outscale, a subsidiary of Dassault Systèmes, and has SecNumCloud certification from the French information security agency ANSSI. As of April 2026, the Suite had been tested by around 40,000 regular users from different departments before general implementation. The French government also announced that it plans to migrate its health data platform to a new secure platform before the end of the year.
The geopolitical trigger
The European Parliament called on the European Commission to reduce dependence on American technology giants and prioritize European cloud infrastructure, open source and AI systems. A defense mechanism against US control of critical digital infrastructuremore necessary than ever in the face of the -unpredictable and crazy- policies of the Trump administration that have sown chaos around the world.
France’s announcement is not an isolated event. It forms the basis of a digital sovereignty strategy that the country has been notably promoting since the end of 2024, largely due to the change in relationship with the United States and the laws under which their companies operate. Trump’s tariffs reignited the European push towards cloud sovereignty from April 2025, with companies such as OVHcloud and Scaleway posting record customer growth, as European institutions began actively seeking to reduce their dependence on US providers.
In November 2025, France and Germany convened a joint summit on European digital sovereignty, creating a working group that would present its report in 2026 and recently a group of European technology companies has presented Euro-Office, open source sovereign office automation to reduce dependence on Microsoft software.
France has already been taking steps and last January announced that would replace Teams and Zoom by its Visio communications platform (a video communication tool based on Jitsi, with end-to-end encryption and open source) for its 2.5 million public officials before 2027. The replacement of Windows follows the same logic: «Digital sovereignty is not an option, it is a strategic necessity».
The context of this approach is structural. For example, US cloud service providers control approximately 85% of the European cloud market, and spending on European sovereign cloud infrastructure is expected to more than triple to €23 billion by 2027. Windows monopolizes the use of operating systems, as does Office in collaboration suites. Not to mention artificial intelligence platforms.
The expansion of efforts in Europe to recover its technological infrastructure has gone from being a minority political concern to one fundamental political priority across the continent. France appears to be moving faster than any other EU state when it comes to government IT infrastructure, although there are projects in other countries.
How to migrate to Linux and not go back to Windows
Linux has been the best alternative to Windows for years, whether on consumer, business or public administration desktops. But the directive approved in France is a mandate, not a completed migration. The absence of a specific Linux distribution means that each ministry will have to make its own procurement and compatibility decisions, and experience in public sector IT projects suggests that plans for autumn 2026 will vary greatly in ambition and specificity.
Certain categories of specialized software, particularly in defense, healthcare, and financial regulation, rely heavily on specific Windows applications, which can make it complicated to use alternatives. DINUM has recognized this through the flexibility it has built into its framework, but the question of how many of those remaining dependencies can realistically be resolved with a government-imposed roadmap will only be answered in the next two or three years.
The sovereignty strategy also contains a structural irony that will persist in the short term regardless of the operating system running on officials’ computers. France will replace Windows with Linux, but the continent’s most ambitious technology projects continue to be developed and scaled on top of American cloud infrastructure. Replacing the desktop layer is important, but it is placed on a substrate that American technology companies continue to dominate.
On the other hand, not all migration projects from Windows to Linux have ended up being successful (for different reasons) and the case of Munich stands out. At Microsoft they were aware of the damage that this project could do to their interests if it was successful and became an example for other administrations to follow, so they moved heaven and earth to make it fail.
The situation has changed a decade later. Alternatives, especially open source, are much better suited for replacement. And the commitment to digital sovereignty in Europe is (must) be unstoppable. But it won’t be easy. We will also have to address cloud platforms and everything that is coming from AI. The Mistral AI platform founded in Paris on open weight models is a good example to follow. The degree of digital autonomy they can achieve will depend on the decisions that European governments make now. Digital sovereignty today is not a slogan, it is a strategic obligation for the Old Continent.
