Microsoft's Build 2015 developers conference starts today, and it will provide the best look at Windows 10 and new Windows Apps. It's the biggest event of the calendar year for Microsoft, and the keynote alone will run for 2 hours and 30 minutes. We're expecting Microsoft to focus on Windows, Office, HoloLens, the cloud, and its continued plans for cross-platform apps on iOS and Android today.

One of the biggest announcements will likely be Microsoft's plans for bringing native Android apps to Windows 10. Microsoft will unveil a series of ways it's trying to make it easier for developers to bring their code to Windows universal apps from Android, iOS, or elsewhere. Part of that will include better tools for developers and new ways to closely map the functions of Android to Windows so it’s easier for developers to port their apps with small changes. It might not be the ideal solution, but it could be enough to convince Android developers to list their apps in the Windows Store without a lot of effort.

We'll also hear about Microsoft's plans for the future of Windows across internet of things devices, HoloLens, Xbox One, and even maybe some new type of hybrid phone and laptop hardware. Join us live from 11:30AM ET this morning as we cover every single announcement.
