Maximum PC: Steven Sinofsky, the former head of Microsoft's Windows division who was ousted shortly after the launch of Windows 8, has washed up at Harvard Business School. His new title is "Executive in Residence" and his tasks include research, writing, teaching students product development, planning, collaboration, and more, Sinofsky announced in a pair of Twitter messages. He added the hashtag "sabbatical" to one of his tweets, indicating this is probably a temporary role.
