Microsoft will webcast the opening keynote of its BUILD developers conference Wednesday starting at 9 a.m. PT (noon ET).
The company has not yet revealed the keynote speakers, but with the conference's emphasis on Windows 8.1, it is likely that the Windows division's top two executives, Tami Reller, the group's CFO, and Julie Larson-Green, head of development, will be in the spotlight.
BUILD 2013 runs Wednesday through Friday, and will be held at San Francisco's Moscone Center.
Tickets for the third BUILD conference went on sale in April and sold out within 24 hours. Like 2012's BUILD, prices for this year's edition went for between $1,595 and $2,095.
As it did last year, Microsoft will live stream the keynotes -- a second will take place Thursday, also at 9 a.m. ET, noon ET -- on its Channel 9 website. Other parts of the conference, including some of the developer sessions, will be webcast as well.
With rumors of a major reorganization at Microsoft now in play, analysts will be watching to see which executives take the stage Wednesday for clues about how the software giant will restructure divisions and shuffle management to back up CEO Steve Ballmer's assertion that the company now focuses on services and devices.
It's unlikely Microsoft wants to repeat the events of last year, when Steven Sinofsky, then the head of Windows, appeared on stage at the Windows 8 launch but was ousted from the company less than three weeks later.
Also Wednesday, Microsoft will debut a public preview of Windows 8.1 on its Windows Store. The free upgrade for Windows 8 and Windows RT is to ship in final form later this year. Microsoft may announce a delivery date at BUILD.
