Steven Sinofsky, the president of Microsoft's Windows and Windows Live division, will take the stage Tuesday at 9 a.m. PT to kick off the company's BUILD conference.

Microsoft will webcast both Sinofsky's keynote and a follow-up the next day that will be led by Satya Nadella, who heads the Server and Tools Business division, and Jason Zander, a vice president in charge of the Visual Studio development tools group.

The BUILD keynote speakers were confirmed by Brian Kyle, a Microsoft evangelist, in a blog post today.

Later on Monday, Kyle pulled the original post and replaced it with one much shorter that omitted the names of Sinofsky, Nadella and Zander, as well as a broad stroke list of Windows 8's features. A of Kyle's original post is still accessible via Yahoo.

None of the latter were new, although Kyle did say that Windows 8 would include "support for all the most important apps that people use today." [Editor's note: Emphasis added.]
