China joins Europe in scrapping Windows for Linux

China has ordered some government agencies to abandon the Windows 10 China Government Edition in favor of domestic Linux distributions, according to a Bloomberg report attributed to the country’s Ministry of State Security. The move reflects a broader distrust of American software vendors among non-US governments, with digital sovereignty cited as the driving concern. Beijing had already been working for years to replace foreign technology in sensitive systems with open-source domestic alternatives, and the new directive accelerates that push. Chinese officials cited data security concerns about Windows without providing specifics, according to the report.

Microsoft responded that it was not aware of any security incident affecting the product, which it said continues to receive regular security updates. The specialized Windows 10 China Government Edition is distinct from the consumer version, having been developed by C&M Information Technologies, a joint venture formed in 2016 between Microsoft and state-owned China Electronics Technology Group. That build was tailored to meet Chinese government requirements, including localized activation and update processes, removal of certain consumer services, and support for Chinese cryptographic standards. Its retirement had already been scheduled for February 2027, but that end-of-life date has now been moved to later in 2026.

The Chinese government did not specify which Linux distributions would replace Windows, but the stock prices of two domestic suppliers, Kylin Software and Tongxin Software Technology, known as UnionTech, rose immediately after the announcement. Kylin’s commercial operating system, Kylin OS, and UnionTech’s UnionTech OS, commonly called UOS, were already positioned as desktop and server replacements for Windows in government, state-owned enterprise, and critical-infrastructure settings. Kylin also offers a free, fully open-source version called openKylin, while UOS is derived from the Deepin desktop and the Debian Linux family. Both vendors have focused on institutional deployments rather than the consumer PC market.

Huawei’s HarmonyOS 2, which originated as an Android variant and is now a proprietary mobile and IoT operating system, is also being developed as a PC platform, though it is not expected to be deployed soon. Kylin and UOS are currently the only mature desktop options ready for institutional use, according to the report. The transition will not be simple, as agencies must address application testing, peripheral and driver validation, identity system integration, document-format compatibility, and staff retraining, along with adapting or replacing Windows-dependent line-of-business software.

The report does not detail how the migration will be executed, but the speed of the directive suggests these issues are already being handled within China’s centralized managed desktop infrastructure. The order does not amount to a nationwide ban on Windows, as the restricted, factory-locked Windows Home China 11 remains available, and the scope of the directive has not been disclosed. Still, the direction is clear: China’s government desktop computing is moving to Linux. For US technology observers, the shift underscores how geopolitical friction is accelerating the fragmentation of global software markets, with American operating systems facing increasing exclusion from foreign government procurement.
