China Accelerates Windows Replacement to Reduce US Technology Dependence
China is asking some government organizations to stop using a special version of Windows on certain computers.
The special software was changed to meet Chinese security requirements.
It was made by a company jointly created by Microsoft and a Chinese state-owned technology group.
The software was supposed to be retired in February 2027, but the change may happen sooner.
Chinese agencies are being encouraged to use computer systems made by Chinese companies instead.
These systems are based on Linux, an alternative to Windows.
China says the broader shift is connected to data security and reducing reliance on foreign technology.
Microsoft says it does not know of a security incident involving the customized software.
Windows remains widely used by Chinese consumers, even as government agencies move toward domestic alternatives.
China’s Ministry of State Security reportedly told some state-linked organizations to remove customized Windows 10 from certain computers.
The software was developed by C&M Information Technologies, a joint venture between Microsoft and China Electronics Technology Group.
The customized system was scheduled for retirement in February 2027, but authorities are reportedly accelerating the transition by several months.
Chinese agencies are being encouraged to use domestic Linux-based systems, including Kylin OS and Unity OS, for sensitive operations.
Microsoft said it was not aware of a security incident involving the product and said it continues to receive regular security updates.
