Satya Nadella, take your latest setback in China as a compliment. In the eyes of Chinese leaders, Microsoft isn't a company struggling to recover from missteps of the Steve Ballmer era. Instead, it's a tech industry heavyweight worth punching to make a point -- hence the ongoing campaign against the company and its China operations. In May, the Chinese government announced a ban on installing Windows 8 on new government computers. In July, investigators raided Microsoft offices in the country, and the State Administration for Industry and Commerce said it was examining whether Windows and Office software violated China's antimonopoly law. Now the government may be putting more pressure on Microsoft, this time through allegations of tax evasion, in response to talk from Washington about Chinese cyberattacks. Last Thursday, US National Security Agency Director Admiral Michael Rogers told a congressional committee that several foreign governments have hacked into the energy grid in the US.
