Microsoft Build 2026: AI development with, under and for Windows

Microsoft organizes the developer conference MS Build 2026 on 2 and 3 June 2026. The company thus applies in particular to developers who use their software for Windows-Ecosystem. As in recent years, a lot of artificial intelligence is on the agenda again this year. Concrete Windows development can hardly be found. Again, the development is on top of the list with the help of AI and AI-based helpers. The “Microsoft AI Superintelligence Team” releases seven new AI models into the world. Below is the first reasoning model MAI-Thinking-1 from Microsoft. MAI-Image-2.5 and a flash version of it dominate text-to-image, they should Google Overtake Nano Banana Pro. MAI-Transcribe-1.5 inscribes sound in 43 languages, but streaming is to be added soon. MAI-Voice-2 and a flash version of it operate 15 languages and have received new voice options. On programming GitHub helps MAI code-1. Microsoft mentioned OpenAI in the course not. Lectures treat building, distributing and scaling AI agents with the Windows 365 Cloud PC. A lecture on Windows Subsystem for Linux promises news. To date, all of the few Windows-specific presentations have been concerned with the use of AI tools to develop on Windows and with the operation of AI bots such as OpenClaw. A lecture is coming out: he describes how developers can increase their productivity with the Windows Terminal. Platforms, tools, trust

Much flowery rewrites Microsoft's marketing department, which requires developers to offer the solutions right away. At the end, it is distilled from the need for security of infrastructures and apps as well as accelerated and simplified development. And that not only for partial problems, but full-stack, with tools, models and processes according to the ideas of the developer. Windows should, of course, be the ideal platform for this – you get almost the feeling that the operating system has completely decoupled and become irrelevant for all key contributions to development of and with AI. However, Microsoft announces a new developer configuration: This should provide more flexible and smoother shell and terminal experiences. In addition, agents can be interrogated in local sandboxes: Microsoft talks about making Windows a native agent runtime. As a preview version, there are the Microsoft Execution Containers (MXC) named sandboxes that are to be Enterprise-fit – for example, to run OpenClaw with “security restrictions”. The preview of the GitHub copilot app is intended to make agentic development a native desktop experience for a much wider audience: interested should simply describe an idea or an existing problem, and the app starts and lets multiple agent sessions run parallel and keeps the changes in mind. Each session uses git-Trees so that the parts remain separate. The developers keep control while Copilot takes care of the execution. Developers should be able to create apps in seconds.

For access to databases and services, Microsoft has a backend-as-a-service on offer, previewing the Project Rayfin platform. This should enable development from prototypes to production levels without developers having to take care of the management of infrastructure. New AI hardware also has Microsoft to offer: The Surface RTX Spark is a developer box for permanent workloads. Training, agentic AI pipelines and local fine tuning of models, all this should be done with a load of 100 watts. In it, according to the name, Nvidia RTX Spark with up to a Petaflop AI computing power (unnamed precision) and 128 GB of RAM (unified, i.e. shared with processor). The machine should allow models with up to 120 billion parameters to run locally. Windows Subsystem for Linux 2 (WSL2) with native GPU-Passthrough as well as full CUDA support provides Microsoft preconfigured. In addition, Visual Studio Code, GitHub copilot and numerous other popular dev tools should be pre-installed. Small hook: This developer box should be available only later in the year – and for the first time only in the United States. (dmk)
