Microsoft leadership shake-up as veteran exec departs

Microsoft on Thursday announced a shake-up in its top ranks, including the departure of longtime chief operating officer Kevin Turner for a new job. Microsoft chief executive Satya Nadella said that five executives will divide the duties held by Turner, who played a pivotal role over the past decade as Microsoft shifted from packaged software to programs offered as services in the internet cloud to a gamut of connected devices.

Turner will remain at Microsoft to aid with the transition through this month, then leave to become chief executive officer at global financial firm Citadel Securities, according to Nadella.
