China Central Television, CCTV, has questioned Microsoft’s Windows 8, citing critical security concerns within the software company’s operating system. The state-run news station cited information it claimed was discovered by experts, which say the operating system had vulnerabilities which potentially could compromise a user’s personal data such as phone numbers and banking information. It also accused Microsoft of colluding with the U.S. government to engage in cyber spying. As a result of China’s controversy over the software giant’s latest operating system, the Xinhua news agency reported the country has banned the use of Windows 8 on all central state agency computers.
