Another reason could be that many Chinese government's websites may not be compatible with Windows 8, according to China Business News.

As experts pointed out, the Window 8 ban may provide a rare opportunity. In terms of easy of use and compatibility, domestically developed Linux-based Ubuntu Kylin OS and Neokylin Linux Secure OS can be the alternatives.

Security Times report citing an anonymous industry source said Linux operating systems could be the main substitute of Windows 8, besides Windows 7 or XP.

After the announcement was made public, mainland's information service stocks surged in the Tuesday afternoon trading, with seven stocks hitting the 10 percent daily limit.

Firms that saw the surge in stock price include China National Software & Service Company and Beijing Join-cheer Software Company. China Standard Software Co's Neokylin Linux Secure OS is among the alternatives, and the company is CNSSC's 50 percent subsidiary.

China Business News quoting Sinolink Securities' research report said that there are about 125 million users of Windows XP across China, and the operating system dominantes government and State-owned enterprises with around 70 percent market share.

"Not a single company listed in Chinese A share market has the capability to develop a competent OS to rival Microsoft," China Business News quoted an analyst in a Shanghai securities company.
