France plans to shift public Windows systems to Linux

France plans to migrate state computers to Linux

Minister David Amiel summed it up in one phrase: "regaining control of our digital destiny." The French government plans to migrate state computers currently running Microsoft Windows to Linux, an open-source operating system, to reduce dependence on American technology providers. This measure adds to two others already announced: abandoning Microsoft Teams for Visio, a French tool based on Jitsi with end-to-end encryption, and moving its health data platform to a trusted infrastructure. Paris has not detailed a timeline or which Linux distribution will be used.

Why France wants to leave Windows

The official argument is no longer savings or efficiency. It is institutional resilience. A state that depends on foreign platforms for videoconferencing, medical records, or thousands of workstations is exposed to external pressures and regulatory changes it does not control. The context cited in published reports is the growing instability attributed to the Donald Trump administration since his return to office in January 2025, with sanctions that reportedly reached judges at the International Incivil Court and, according to the same report, led to bank account closures and blocks on technological services for those sanctioned.

In January, the European Parliament approved a report instructing the Commission to identify areas where the EU can reduce its dependence on foreign suppliers. Software choice ceases to be just a procurement decision.

The real problem: thousands of programs and thirty years of inertia

Accumulated experience in administrations that have already tried points to a concrete wall: it is not the operating system, but the applications. AutoCAD, billing software, specific clients, and a long etcetera only run on Windows. User and equipment management drags along decades of domain controllers and scripts that no one knows how to replicate. Who takes responsibility for setting up a network drive in Linux? What if a shared file is peine from two systems at once?

Some argue that most current administrative software are web applications that care little about the operating system because access is via browser. The problem is the remaining 1%: critical COBOL applications accessed via console that have not been touched in decades. Migrating that is not changing systems; it is rebuilding foundations.

The Zaragoza precedent and training costs

According to a circulating account, in Zaragoza, during Mayor Belloc's tenure, they migrated to Linux and paid for courses and per diems for civil servants. Months later, many did not know a single command and they reverted to Windows. The episode is cited as an example that training and organizational inertia weigh more than political decisions.

The learning curve for millions of public workers and the need for an army of technicians trained in another environment are costs that no announcement mentions. The complete calculation, including license fees, training, and support, is what never appears in the press release.

The technical debate: reliability, servers, and who audits

The discussion quickly turned technical. Against those who defend that Linux is the de facto standard in servers and supercomputers, testimonies appear of boot failures on personal devices after months of operation. The response is that a bootloader problem always has a solution, although it requires knowledge that the average user does not have.

Another objection notes that auditing code is not within everyone's reach: if development is done by contractors, the real capacity for audit is doubtful. And some recall that free software belongs to no company, although its commercial derivatives do have owners.

What would be needed so it doesn't remain just an announcement

Dominant skepticism suggests that without a calendar, without a chosen distribution, and without a supplier plan, the announcement functions as a political message. The EU would have to finance and manage the transition, not just identify it. And real change would start in primary education, with a decades-long project that no electoral cycle withstands.

Meanwhile, the lingering question is the same one asked by a participant: why do private companies keep their servers on Linux while public administrations insist on Windows. The answer is not technical.
