Ni Guangnan, a scholar at the Chinese Academy of Engineering, wrote the report and said that the government's decision is final and no other statement will be released.
"China's smart terminal operating system industry alliance commissioned some authoritative institutions [to study] the similarity between Windows 8 and Windows 10 in 2015. They concluded that the cores of the two operating systems are basically the same," according to the report.
An expert said that the additional cloud feature seen in Windows 8 and 10 make data vulnerable to leaking.
"Windows 8 and Windows 10 have added the function of cloud storage, which facilitates information storage but risks information leaks," said Xiang Ligang, CEO of telecommunication industry portal cctime.com.
The state-run China Electronics Technology Group Corp. formed a partnership with Microsoft in Sept. 2015. Microsoft was expected to develop a version of Windows 10 that was specific for use of Chinese government institutions.
In September 2015, Microsoft and Chinese government developers formalized the partnership and called it C&M Information Technologies.
They came up with Windows 10 Zhuangongban in March 2016.
Fu Liang, a Beijing-based independent technology expert, said, "Other countries in the world also impose some restrictions on Windows not just for information security but also to protect their own industries."
The expert said that the lack of protection has led Russia to plan on banning Windows from their country.
Technology specialists think that China still has to catch up to developing its own operating system that would be at par with Windows.
"The market cannot trade technology, Ni explained, "It all depends on our own research and development."
Meanwhile, Chinese users have been criticizing Microsoft for forcing system upgrades.
Zhao Zhanling, a legal adviser for the Internet Society of China, said, "The company has abused its dominant market position and broken the market order for fair play."
