Microsoft has been improving many different areas of the Windows 10 experience recently, and the upcoming Anniversary Update will add even more new features, but there is one variant of Windows 10 that hasn't received as much attention: Windows 10 Mobile.

Windows chief Terry Myerson, speaking to The Verge, stated at Build 2016 that Windows 10 Mobile is not a focus for Microsoft over the coming year. According to him, the mobile variant of Windows is "part of the family but it's not the core of where I hope to generate developer interest over the next year."

Myerson even admitted that the user base of Windows 10 Mobile isn't significant enough: "if you wanted to reach a lot of phone customers, Windows Phone isn't the way to do it." Instead, the best way to reach customers is by developing apps for 9 to 30-inch screens (in other words, tablet, laptop and desktop users), while Xbox and HoloLens provide platforms to do "new and exciting things".

These statements from Myerson highlight why Microsoft has been focusing on other platforms, even rival mobile operating systems like Android and iOS, rather than Windows 10 Mobile. The potential target audience is simply greater on Windows 10 for desktops and rival mobile platforms, and with limited resources Microsoft wants to ensure these platforms deliver a great experience.

However, Microsoft isn't giving up on Windows 10 Mobile entirely. Although the mobile version of Windows isn't the company's focus this year, Myerson says that they're "going to do some cool things with phones" in the future. Whether that means Microsoft has a Surface Phone up their sleeves, only time will tell.
