China's market regulator is warning Microsoft not to interfere with an ongoing anti-monopoly probe of the company.
The State Administration for Industry and Commerce has begun inquiries into the company's corporate vice president, Mary Snapp.
Investigators previously launched a probe into Microsoft China and three of its branches in Shanghai, Guangzhou, and Chengdu.
Microsoft China has issued a statement, saying it has always abided by laws and regulations in China and will cooperate with the investigation.
Microsoft is accused of failing to fully disclose anti-competition information about its Windows operating system and its Microsoft Office application.
