Microsoft is planning to combine its Windows Phone Store and Windows Store into a single app store. Sources familiar with the company’s plans have revealed to The Verge that Terry Myerson, head of the operating systems group, confirmed the move in an internal company meeting today attended by thousands of Microsoft employees. We’re told that Myerson committed to the “next releases” of Windows and Windows Phone, which we understand to be Windows Phone 8.1 and a special update planned for Windows 8.1. Both are due to be ready in spring 2014. Myerson didn’t reveal how the single Windows Store would work, nor whether Windows Phone apps will run on Windows in the new model. The Windows head previously publicly commented that he sees the future of Windows RT in phones and small tablets.
