Today, Microsoft announced a major shift in focus for its personal assistant, Cortana: she's getting out of the consumer gadget business and focusing on productivity. The new version of Cortana will debut with the next major update to Windows 10, expected to roll out in April.

Microsoft is tightening access to Cortana considerably. First and foremost, no more Cortana use for anyone only using local accounts. Cortana access will only be available to those logged in with school work domain accounts or Microsoft online accounts—Windows 10 users sticking to local accounts only will also be out of luck.
