Domestic alternatives and market reaction: The directive triggered a rally in domestic OS and software stocks (Hunan Kylinsec, Archermind hit 20% limits; China National Software rose ~10%) as agencies were urged to migrate to Linux-based domestic systems such as Kylin OS and UnionTech's UOS, requiring compatibility testing, retraining and application migration. The move is part of a broader push to replace foreign hardware and software in sensitive sectors.

Ministry orders accelerated removal: In mid-August 2026, China's Ministry of State Security instructed some state-linked entities to uninstall the customised Windows 10 build, moving up a planned retirement originally set for February 2027 to later in 2026 and citing data-security concerns. The directive arrived weeks before a planned Trump‑Xi meeting and reportedly surprised some state agency staff; authorities have not disclosed specific vulnerabilities.

Mainstream support ended globally: Microsoft ended mainstream support for standard Windows 10 in late 2025 after Windows 11's launch, leaving the China Government Edition as the only Windows version officially approved for Chinese government use. Microsoft continued to provide security updates for the product while remaining a significant cloud and AI provider in China.
