Microsoft's Build 2015 event is about to get underway, with a livestream available for online viewing.
You can tune in to the developer conference keynote speech on Microsoft's website (no embed, sadly). The keynote is set to last for two and a half hours, and is Microsoft's biggest event of the year.
The speech is planned for 11:30 a.m. EST, but is slightly late to start--it should begin any minute now. Windows 10 is expected to take the focus today, as anyone who follows the company's plans may expect.
Microsoft's new operating system is set for release this summer, so time is growing short for Microsoft to reveal and discuss any features it has not yet covered. We're likely to see several Windows apps in action, as well as integration across PC, mobile, and tablet.
Given the developer focus, don't necessarily expect to see a plethora of general user features. Instead, Microsoft will demonstrate how embracing and using its platform will make it easier for app creation or platform transfer for developers.
