Microsoft is doubling an earlier job cut plan, part of Chief Executive Officer Satya Nadella's move to pare the company's smartphone ambitions. About 2,850 positions worldwide will be eliminated in fiscal 2017, the company said Thursday in a regulatory filing. That's in addition to 1,850 job cuts, primarily in the smartphone hardware business and sales, announced in May.

Microsoft failed to make significant market share gains against Apple's iPhones and Google's Android operating system. Windows phones had less than 1 percent of the global smartphone market in the first quarter, according to Gartner.
