> The company is breaking Windows in pieces. The platform technology, on which Microsoft’s partners build their own devices, apps and services, will now fall under Scott Guthrie, who runs the Azure business. Mr. Guthrie’s unit, called Cloud + AI Platform, will also include the company’s mixed-reality business, including Microsoft’s Hololens device, as well as its artificial-intelligence business.
Maybe someone with insider knowledge will comment, but it looks like Windows is far from being a priority for Microsoft.
