Microsoft is using Build 2026 to send a clear message: the spotlight is on AI agents, Copilot, and Azure AI Foundry, not on Windows 12. The company has already made it clear that there is no Windows 12 announcement on the keynote agenda.
That makes this year’s developer conference feel less like a product reveal stage and more like a roadmap for AI-first development. Microsoft Build 2026 opens in San Francisco on 2 June and runs through 3 June at the Fort Mason Center, with Satya Nadella’s keynote scheduled to stream at 9:30 a.m. PT.
AI takes the center seat
The session themes confirmed for the event point strongly toward agentic AI workflows, GitHub Copilot development, Azure AI Foundry updates, native AI development for Windows, and tools for responsible AI. Microsoft is not treating AI as a side topic here; it is framing it as the core of the entire conference.
That approach suggests the company wants developers to build applications and AI agents on top of its existing ecosystem rather than wait for a new operating system. The messaging also fits Microsoft’s recent push to make AI development more connected, more governed, and easier to move into production.
Azure AI Foundry stays in focus
Azure AI Foundry appears repeatedly across the Build session catalog, making it one of the most prominent pillars of the event. Microsoft Foundry already supports models from OpenAI, Anthropic, Mistral, DeepSeek, and others.
At Build 2026, Microsoft is expected to show how developers can route workloads across models, control costs, and move agents into production. That cost-control angle has become a consistent part of Microsoft’s enterprise communication, alongside attention to token consumption and responsible AI policies at the platform level.
Windows is present, but in a different role
Windows is still part of the Build story, though not as a new operating system reveal. A dedicated Windows local AI track is confirmed, and Microsoft continues to expand on-device AI through Copilot Runtime in Windows 11.
A Windows 11 Insider update on 30 May also hinted at the direction of the platform. It introduced a fully customizable Start menu and expanded local AI capabilities, reinforcing the idea that the conference is about strengthening Windows as a developer platform rather than launching Windows 12.
Copilot moves beyond the editor
GitHub Copilot is another major theme at Build 2026. Planned sessions will cover agent-based coding workflows, multi-agent support inside VS Code, and deeper integration between GitHub and Azure.
Copilot CLI reached general availability in March 2026, and Build is expected to extend that work into multi-agent terminal workflows. That shift shows how Microsoft is trying to push its coding assistant beyond the editor and into broader developer operations.
Agent control and enterprise readiness
Microsoft Agent 365 is also among the important highlights. The enterprise control platform for AI agents reached general availability on 1 May 2026, and Build is expected to build further on that foundation.
Taken together, Agent 365, Azure AI Foundry, Copilot, and Windows local AI point to a single direction. Microsoft is building a stack where developers can create, manage, and run AI agents across the cloud and directly on Windows devices.
How to watch
Satya Nadella’s keynote will be available for free on build.microsoft.com and on Microsoft’s YouTube channel starting at 9:30 a.m. PT on 2 June. All sessions will also remain available on demand after the event ends.
With the agenda already laid out, Build 2026 is shaping up as a Microsoft AI developer roadmap rather than a surprise launch event. The biggest takeaway is not a new Windows version, but the company’s push to make AI agents and Copilot central to how software gets built.
