France has taken a decisive step toward digital sovereignty, announcing plans to migrate government workstations from Microsoft Windows to Linux.
The move was formally declared during an interministerial seminar held on April 8, 2026, organized by the Interministerial Directorate for Digital Affairs (DINUM), the National Cybersecurity Agency of France (ANSSI), the Directorate General for Enterprises (DGE), and the State Procurement Directorate (DAE).
The seminar, convened at the initiative of the Prime Minister and the Minister Delegate for Artificial Intelligence and Digital Affairs, brought together ministers, government departments, public operators, and private sector stakeholders. Its central objective is to accelerate France’s strategy to reduce its digital dependencies on non-European technology vendors.
The Windows-to-Linux Transition
DINUM officially announced its exit from Windows, signaling a full migration to Linux-based workstations across state infrastructure. While a specific Linux distribution and rollout timeline were not disclosed in the seminar’s initial announcements, ministries will be required to formalize individual transition plans by fall 2026.
The migration scope spans workstations, collaborative tools, antivirus software, artificial intelligence platforms, databases, virtualization environments, and network equipment.
This shift carries significant cybersecurity implications. Moving away from a proprietary, closed-source OS reduces the government’s exposure to vendor-specific vulnerabilities and foreign intelligence risks, a concern that ANSSI has long emphasized in national cyber defense guidance.
The Windows migration is part of a wider push toward European digital tools. The National Health Insurance Fund recently announced the migration of its 80,000 agents to interministerial digital platform tools Tchap (secure messaging), Visio (video conferencing), and FranceTransfert (document transfer).
Additionally, the French government confirmed last month that its national health data platform will migrate to a trusted sovereign cloud solution by the end of 2026.
These moves follow Prime Minister directives, including circulars on digital public procurement and mandatory adoption of the “Visio” video conferencing tool as a Windows-independent collaboration standard.
Rather than a purely top-down mandate, France is forming public-private ministerial coalitions to execute the transition. DINUM will coordinate an interministerial dependency-reduction plan, leveraging digital commons and interoperability standards such as the Open-Interop and OpenBuro initiatives.
The State Procurement Department (DAE) is simultaneously mapping existing technology dependencies to establish quantified reduction targets with clear timelines.
The first “Industrial Digital Meetings” are scheduled for June 2026, where DINUM plans to formalize a public-private alliance for European digital sovereignty.
This migration represents one of the most significant government-level OS transitions in recent European history, setting a potential precedent for other EU member states prioritizing technological independence.
