Satya Nadella aims to make Microsoft mighty - and mindful

Satya Nadella, the Microsoft CEO who kept the company relevant as its primary PC software business faded, could write a book about the challenges he faced. And he has ... but it's not a tell-all memoir. Instead, Nadella, who has worked at the company since the early 1990s, has positioned himself as the embodiment of the story Microsoft wants to tell about its transformation into a forward-thinking outfit focused on artificial intelligence, cloud software, virtual worlds and quantum computing. "Microsoft is known for rallying the troops with competitive fire," Nadella writes in "Hit Refresh," his new autobiography. "The press loves that, but it's not me."
