Microsoft is leaning into an AI-first future at Build 2026, but it is keeping many of the most practical sessions for people who made it to Fort Mason. Satya Nadella will deliver the opening keynote at 12:30 PM ET, 9:30 AM PT on June 2, streamed on Microsoft’s Build site and the company’s developer YouTube channel, and the conference continues through June 3. Remote viewers should claim the free digital pass to reach most livestreamed content, session recordings and the event scheduler; in-person tickets, now sold out, included extra breakout sessions, hands-on labs, demos and partner access that may not be recorded.
The stage at Fort Mason sat half-lit as the crowd settled in, a row of laptops aglow in the dim, and the feel was equal parts product launch and developer bootcamp.
The read on Build 2026 is straightforward: Microsoft wants to show developers how Windows and its platforms fit into an AI-first future, but it's also fencing some of the conference’s most valuable practical work behind in-person access. The company bills the keynote as a tour of "how Microsoft is creating new opportunity for developers across our platforms in this era of AI," and the program backs that up with a heavy emphasis on agentic AI, AI-assisted app development and Windows-native engineering. At a headline level Microsoft lists roughly 375 session options across the two-day program, but several outlets and accounts have noted that many talks, labs and partner sessions are reserved for on-site attendees and that some in-person sessions may not be recorded.
Start with the easy part. The opening keynote, featuring Satya Nadella and other senior leaders, goes live at 12:30 PM ET, 9:30 AM PT on June 2 and will be available on Microsoft’s Build site and the company’s developer YouTube channel. But microsoft is streaming the keynote without requiring sign-up, though it asks developers who want access to the broader streamed slate, session recordings and the personalised schedule to claim the free digital pass on the Build registration page.
The free digital registration provides access to livestreamed keynotes, many online sessions and a session scheduler planner. That planner is the practical benefit for remote attendees: it helps prioritise from hundreds of talks and map a viewing schedule across the two days. If you want the hands-on components, demos or partner interactions that often make conferences useful for project work, note that in-person admissions included those elements and were priced at $1,099 when sold, and on-site attendance remains the only way to get into some breakout sessions and labs that Microsoft limits or doesn't record.
Behind the stagecraft is a technical agenda centred on AI tooling and Windows platform work. Microsoft has used Build to push developers toward native Windows app performance, and this year that push is being framed around AI-enabled development workflows and improved ARM support. Company messaging and the session catalogue promise talks on Windows agents, porting apps to run natively on ARM and agent design topics such as "agent supervision," plus sessions on using GitHub Copilot-style tooling to speed native Windows app development.
Those themes dovetail with recent product and partnership moves. Microsoft has announced a Surface Laptop Ultra slated for this fall that will run on NVIDIA’s RTX Spark platform, and the firm has been talking about NVIDIA’s N1x chip and RTX Spark as a route to workstation-class performance for Windows on ARM.
Company executives have also teased "something new for developers" in pre-event messaging. Several social posts from Microsoft and partner accounts referenced Computex and used the phrase "a new era of PC," which suggests coordination between hardware announcements and Build sessions but doesn't by itself confirm a product roadmap.
The timing of those reveals matters. Microsoft adjusted some AI placements after user backlash to Windows 11, reworked its enterprise Copilot offering and removed an AI assistant from some apps in April 2026. The company also reshaped its relationship with OpenAI into a more open partnership in April 2026. Those moves inform the tone of Build’s dev-focused AI messaging: there's a visible corporate effort to balance aggressive AI product pushes with clearer guidance for enterprise deployment and native app performance promises for Windows developers.
Supporters argue that Build’s focus is necessary. They see the conference as a developer-first intervention to resuscitate native app ecosystems on Windows, especially by speeding porting and improving ARM compatibility with tools that lean on AI. Critics counter that the practical work that actually moves projects forward is too often on-site only. The tension is real: free digital passes let many watch keynotes and some sessions, but the hands-on labs, partner briefings and unrecorded deep dives are confined to a smaller, paid and now sold-out audience.
For developers watching from afar there are two pragmatic choices. First, take advantage of the free registration to capture livestreams and use the scheduler planner to build a tight watchlist from the roughly 375 sessions. Second, follow the recorded keynotes and the sessions Microsoft elects to publish after the event, while staying aware that some technical demonstrations and partner conversations may only exist for attendees who were physically at Fort Mason.
For enterprise customers and platform teams the stakes are concrete. They will be watching comments about Copilot enterprise features and deployment models after April’s changes, and they will look for technical guidance on agent supervision and native performance tuning. For the broader developer community the test will be whether Microsoft publishes the instructional content needed to make the new tooling and ARM guidance broadly useful, or whether the most operational material remains in rooms that were only open to those with on-site passes.

The Build 2026 keynote begins at 12:30 PM ET, 9:30 AM PT on June 2; register for the free digital pass on Microsoft’s Build registration page to access the streamed keynotes, many sessions and the session scheduler over the conference run through June 3. After the event, check Microsoft’s session library and partner channels for recordings, because some hands-on labs and partner briefings may remain unpublished.
