Where and when to watch Microsoft's #Build2017 day one keynote

Starting at 8 am PT tomorrow, May 10, Microsoft's top leadership – including CEO Satya Nadella – will begin the annual three-day conference. Focusing on new tools, new partner announcements, and new directions for Windows 10 and related technologies, Microsoft plans to give its developer base a shot in the arm.

Here are the main things you need to know:

  • Day one keynote with Nadella: Begins at 8 am PT / 11 am ET. (Find your local time here). This is the big Build event where most of the major news drops.
  • Day two keynote with Executive Vice President of the Windows and Devices Group Terry Myerson: Begins at 8:30 am PT / 11:30 am ET. (Find your local time here). Normally, Day one is the "big deal" day, and day two is more focused on things like the cloud and Azure. This year is different, however, and we're expecting big Windows 10 news to fall on the second day, so you should plan to watch both keynotes this year.
  • What we expect to see from Microsoft at Build 2017: Read our predictions and expectations article for insight on what may be coming this week
  • Windows Central Live Blog for Build 2017: Bookmark this page to view in our live blog of both the day one and day two keynotes! There will also be a community chat where you can discuss the news live. And we'll include Microsoft's video embed for the keynotes.
  • Watch the live stream: Again, we'll embed the video stream in our live blog, but you can find the main channel on Microsoft's site (opens in new tab), as well.

Just to be clear, there are two significant events for those of you following the event from afar: the day one keynote (Wednesday, May 10) and the day two keynote (Thursday, May 11). The first one is the long, three-hour version, while the second keynote is shorter, at just 90 minutes, but it will focus more directly on Windows 10.

  • something, something mobile phone
  • Don't you mean "ultimate mobile device"?
  • My birthday, on Thursday! 😌
    Hope something great is announced! 😁
  • yeah they're going to announce the Mohammed fleshlight
  • I hope to hear something about mobile
  • Big day for windows phone fans🤔
  • Every time "mobility" is mentioned take a shot of tequila. Every time "Microsoft phone" is mentioned drink the whole bottle. *Why am I still sober?*
    😢😢😢
  • because you spazz to often 😎
  • I think they will talk about https://www.videobreakdown.com in //BUILD/ 2017 because Video Breakdown will be down on May 10th. When you open the site It will say "Video Breakdown will be offline from May 9th, 1am PST to May 10th, 8am PST, in preparation for some exciting changes".
  • Hmm, who owns the domain?
  • After some research, it seems very feasible!
  • When will we see the "build" section in the apps? It was awesome last year ;)
  • I don't understand isn't ET supposed to be European Time? And that would be at 5pm not 11am. I see this every time you post an event and every time I'm wondering. Does someone know?
  • Nevermind, it's eastern time.
  • Eastern Standard Time (UTC-05:00)
  • Actually, it's currently Eastern Daylight Time, not Standard Time.
  • At least some clues about new mobile os...
  • Anyone else receive a WC newsletter about Build?
    Doesn't link to anything, unless the article hasn't been published yet
    "Microsoft WILL address mobile at BUILD - but not how you expect"
  • I hope now Good news ..for future and not only dreaming..after Apple and Google in this line of business.. No enough time to dream.😀 good luck 🍀
  • Only three _HOURS_? :P
  • My bet: The words Android and iOS will be mentioned more than Windows mobile.
  • Time to get over it.   WM is DONE!
  • prepare you lie detectors as they will go highwire during this build :))
  • AH HA HA HA...nice one MMGN!
  • Lord it starts at 3am here. Guess I won't be watching the livestream, unlike edu. Tell us all about Cortana/bots/neon thx!
  • Mobile announcement: We are working hard to get all of our apps on all of the popular mobile OSes - Android and IOS. Next question?
  • I just don't think we're going to get the mobile answers we're all searching, hoping for. Microsoft really needs to restate its commitment and mission with UWP and how it intends to attract devs to create / port / convert apps from iOS/Android and traditional x86 applications to the Windows Store.  They have already drawn a line in the sand with Windows 10 S but without a seismic shift of sheer effort and determination to breakthrough with UWP, it won't matter what happens in the mobile space as there'll be no OEMs or devs or consumers or partners left to attract to the platform beyond the pitiful efforts we've seen so far.  I think all we'll get after the fanfare is more of the same rhetoric - all the tools, support, IDEs, infrastructure are already there. Somehow they need to push this hard to gain momentum or come with some new innovation and ideas that make a compelling story that encompasses and goes beyond mobile.  It's a big ask and right now, I can't see it. But here's to hope.
  • Not being a coder I still love build and having channel 9 stream in the background while I'm working having absolutely no clue what they're talking about, but I still find it fascinating
  • Running the 950 now, just sold the XL. Great phones. Hey, all the functionality I need and everything just works.
