China orders state agencies to uninstall Windows 10 for security
The Digital Divide: China Pulls the Plug on Customized Windows
In a high-stakes move signaling a deep commitment to digital sovereignty, China’s Ministry of State Security has issued directives demanding the removal of a customized version of Windows 10 from state-linked organizations. This order isn’t just a routine software update; it represents a strategic acceleration of a broader technological pivot, forcing a shift away from global standards and toward a wholly domestic computing ecosystem.
The focus of this directive is a specialized version of the operating system developed by C&M Information Technologies, a joint venture born from a partnership between Microsoft and China’s state-owned China Electronics Technology Group. This customized edition was designed specifically for government use, featuring unique modifications that set it apart from standard consumer releases. Among these changes, the software stripped out consumer-facing components like OneDrive, disabled certain native functions, and allowed government users to substitute Microsoft’s standard cryptography with domestic Chinese encryption algorithms.
This specific software, which first piloted among entities like China Customs and Shanghai’s Commission of Economy and Informatization, occupied a unique niche. It existed as the only officially sanctioned Windows version for Chinese government use following Microsoft’s decision to end mainstream Windows 10 support globally in October 2025. Even as global support evaporated, this state-sanctioned edition remained the standard for government operations.
The move reflects a powerful trend sweeping through China’s technology sector: the complete decoupling from foreign technology stacks. This initiative follows previous government mandates, such as the 2014 ban on Windows 8 in procurement and the 2022 order to scrap foreign-branded computers entirely. The resulting demand has fueled an aggressive push for homegrown alternatives, with domestic stacks like Kylin V10, UnionTech’s UOS, and Huawei’s HarmonyOS 5 laptops rapidly absorbing the market.
The ambition is to build an entirely self-sufficient domestic infrastructure, reaching deep into the silicon with homegrown CPUs and operating systems, exemplified by devices like Huawei’s Qingyun desktops running the domestic Kirin 9000X chip. This massive internal migration is redefining how Chinese government and state entities manage data and infrastructure, emphasizing control over security and functionality.
While Microsoft maintains that there are no security incidents affecting this specific product and continues to provide regular updates, the underlying tension remains clear. The directive underscores a future where national security concerns directly dictate which operating systems and security protocols are permitted within the nation’s sensitive networks.
