The Chinese government has unexpectedly accelerated its digital sovereignty strategy in public administration. Through a directive issued by the Ministry of State Security , authorities have ordered various entities linked to the state apparatus to immediately uninstall Windows 10 Government Edition from their workstations.
The measure breaks with the official timetable that envisioned a phased withdrawal originally set for February 2027, bringing the deadline forward to the last months of 2026. The justification focuses on data protection and the prevention of possible unauthorized access to confidential information.
The reaction of financial markets in the Asian country was immediate after the ministerial order was announced. Shares of major companies specializing in the development of local infrastructure software and operating systems saw significant increases on the Shanghai Stock Exchange.
Vendors such as Hunan Kylinsec and Archermind reached the 20% daily limit allowed by the stock exchange, while China National Software saw a 10% increase. Technology sector analysts interpret this behavior as confirmation that replacing Western technology with domestic open-source alternatives will cease to be a technical recommendation and become an institutional mandate.
The Decline of Windows 10
Windows 10 China Government Edition emerged from agreements signed in 2016 with the creation of CMIT (C&M Information Technologies), a joint venture between Microsoft and the state-owned conglomerate China Electronics Technology Group Corporation (CETC). The goal of this alliance was to adapt Windows 10 Enterprise to Beijing's security regulations . To achieve this, cloud services like OneDrive were removed, auxiliary telemetry features were omitted, proprietary Chinese encryption algorithms were implemented, and patch management and activation were transferred to local servers controlled within the country.
Despite these concessions, the platform has failed to allay the Chinese government's mistrust . When asked about the removal order, Microsoft stated that it was unaware of any security incidents affecting this specific product and confirmed that the edition continued to receive regular support patches. However, for Beijing, the end of Windows 10's standard support lifecycle in 2025 and the reliance on Extended Support Units (ESU) programs until 2027 have weakened the justification for maintaining foreign software on critical state-owned systems, leading them to opt for a forced removal before the product's lifecycle expires.
Kylin and UOS
The departure of Windows paves the way for Linux distributions specifically designed for China's public and private sectors. The leading candidates to absorb this workload are Kylin OS and UnionTech OS (UOS).
Kylin, developed by Kylin Software, has a strong presence on corporate servers and desktops , and also offers an open-source, community-driven variant called openKylin. UOS, developed by UnionTech, is based on Debian and uses the Deepin desktop environment, optimized for government office environments. Huawei is also making progress with HarmonyOS for personal computers, although its institutional deployment is less advanced compared to the Linux-based solutions.
The Chinese government has been pairing the adoption of domestically produced operating systems with locally manufactured hardware, such as Huawei's Qingyun series of laptops running on the Kirin chipset. The stated goal of government agencies is to close the control gap across the entire value chain, ensuring that the microprocessor, operating system, and corporate applications all meet rigorous domestic security audits.
Challenges and actual scope
Mandatory migration in government agencies is not without its considerable difficulties. Replacing the operating system requires auditing drivers for legacy peripherals, rewriting internal management tools developed exclusively for the Windows API, ensuring compatibility with standardized formats, and training a significant number of administrative staff. Nevertheless, the Ministry of State Security seems to consider these transition costs acceptable given the risk they attribute to maintaining Western systems in strategic departments.
It is important to note that this government directive does not amount to a blanket ban on Windows in the Chinese civilian market. In the home and private business sectors, Microsoft systems continue to dominate the desktop market with a share exceeding 85%, with official adapted editions such as Windows 11 Home China remaining available. The ministerial order focuses exclusively on government agencies , state entities, and critical infrastructure sectors, where government and civilian software will operate in entirely separate ecosystems.
