Microsoft Build, often written as //Build/ is a yearly developer conference hosted by the Microsoft Corporation. In the past, the event focused just on developer tools and announcements related to developer relations, but in the last few years, Microsoft has consolidated its conferences, making Build a sort of catch all event.

Build 2015 is being held again in San Francisco, California at the Moscone Center. It occurs from April 21 through May 1. Registration for the event takes place on January 22, 2015. The event has two days of keynote speeches in the morning from high-level Microsoft executives, with developer sessions happening throughout the day until 5 PM PT.

For 2015, Windows 10 is likely the primary focus of Build. Microsoft is likely to detail final SKU information, release dates, public previews, and new Windows 10 developer tools during the three-day affair. Likewise, new hardware, especially pertaining to high-end Lumia line of smartphones, may also be announced.

Previously, in 2014, Microsoft announced at Build Windows Phone 8.1, Cortana, the Lumia 630, the Lumia 930, SensorCore, SDK Development tools, and Living Images. Plans for the Windows operating system were also announced, although some of the features like the new Start Menu were pushed into the Windows 10 development cycle instead.

Windows Central will be at Build 2015 for live coverage all that week.
