Netherlands Moves Government Systems From Windows to Linux for Digital Sovereignty

The Netherlands has begun transferring government systems from Windows to Linux, testing a NixOS-based desktop environment under a project called Digitaal Autonome Werkomgeving Overheid (DAWO).

Geopolitical Triggers and Digital Sovereignty

The push toward digital autonomy gained urgency in early 2025 following United States sanctions against the International Criminal Court (ICC) in The Hague. Innovation manager and security expert Victor Gevers explained to Tweakers that the sanctions prompted Microsoft to cut off the ICC’s chief prosecutor from essential services such as email.

That disruption demonstrated to Dutch authorities that access to critical IT infrastructure could depend on foreign government policy directions. In response, the Dutch government pursued digital sovereignty to retain control over domestic digital infrastructure and open-source standards. A broader policy introduced in July 2026 instructs public organizations to evaluate geopolitical risk and vendor dependence before adopting public cloud services, discouraging critical entities from storing data outside the European Union or European Economic Area.

Pilot Implementation and NixOS Architecture

Participating agencies are testing the environment on a small number of computers, including setups used by elected council members. Officials have not established a fixed timeline for removing Windows from all government workstations. Administrators are utilizing NixOS to power the proposed desktop environment. This model allows administrators to revert to previous system generations when updates fail rather than rebuilding workstations manually.

Migration Challenges and European Trends

DAWO developers face substantial integration hurdles typical of large operating-system migrations. Engineering teams must ensure compatibility for printers, smart-card readers, VPN clients, accessibility tools, identity systems, and line-of-business applications. Office compatibility remains a primary hurdle, requiring solutions for Microsoft Excel macros, document templates, and Microsoft 365 integrations.

The Dutch migration follows similar open-source transitions in other European nations. Denmark’s government moved from Windows to Linux in 2025, followed by France and Switzerland earlier in 2026. Industry observers note that these sequential migrations strengthen the broader free and open-source software (FOSS) ecosystem, creating a potential snowball effect that encourages more European public sectors to phase out proprietary US software products entirely.
