Microsoft Build 2026: All the news about Windows, AI, RTX Spark, and more

Microsoft's annual developer conference is happening right now in San Francisco, and the company is going big on AI and Windows updates. The keynote started streaming at 12:30PM ET, and early reports suggest we're getting new AI models, agentic tools similar to OpenClaw, and a Copilot "super app" that could consolidate Microsoft's AI offerings.

The Surface Laptop Ultra just got announced with Nvidia's RTX Spark chip, marking another push into Windows on ARM territory. This follows the pattern we've seen with Qualcomm's Snapdragon chips, but Nvidia's gaming and AI credentials could make this more compelling for developers and power users.

Windows 11 is getting some major changes that have already started appearing in preview builds. Microsoft is also rolling out a new developer optimized Windows that embraces Linux even more, plus a mini Surface dev box that's apparently better than what Qualcomm managed to ship.

For anyone building with AI tools, the agentic capabilities and new models matter most here. If Microsoft is moving toward agents that can actually execute tasks across apps, that changes how you might integrate Copilot into workflows. The super app angle suggests they're consolidating their scattered AI products into something more cohesive.

The Windows on ARM story is relevant if you're developing cross platform apps or dealing with performance constraints. More ARM options with serious GPU power could finally make it a viable alternative to x86 for AI workloads.
