Microsoft Build 2025 Recap: 13 Big Announcements You Shouldn’t Miss
Microsoft is doubling down on Agentic AI, and the recent Build 2025 was a reflection of that. It was a full-blown roadmap to the “agentic” future. The company has announced AI agents that automate and improve workflows across products, platforms and the web. If you are overwhelmed with all the information about Build 2025, don’t worry; you have landed on the right page. In this story, I have compiled all the major announcements from Microsoft Build 2025. So, without further ado, let’s get started!
Copilot Becomes a Full Coding Agent
GitHub Copilot is no longer an assistant; it has become a peer programmer. It can now autonomously handle bug fixes, feature additions, and code maintenance. Developers can assign issues, and Copilot will complete these tasks independently.
In addition, Copilot Studio now supports multi-agent orchestration. It allows multiple AI agents to collaborate on complex, cross-functional tasks, like streamlining employee onboarding across IT, HR, and marketing.
Microsoft 365 Copilot Tuning and Multi-Agent Orchestration
Microsoft 365 Copilot now features a low-code tuning tool, which allows organizations to customize Copilot using internal data and workflows. AI assistants can draft documents, summarize meetings, and automate emails tailored to specific business needs. Multi-agent orchestration in Copilot Studio lets several AI agents work together, improving collaboration and automation across tools like Word, Excel, Outlook, and Teams.
Azure AI Foundry and Windows AI Foundry
Azure AI Foundry also got some big upgrades. It now supports over 10,000 AI models, including open-source and proprietary options from Grok, Hugging Face, Meta, and Mistral. It also allows developers to select and fine-tune models for business-specific needs.
Moreover, Windows AI Foundry (formerly Windows 11 Copilot Runtime) is now the local platform version. It enables model selection and deployment across devices and the cloud. Besides, a local version for Mac is also available.
NLWeb: Natural Language Web Protocol
Microsoft introduced NLWeb, an open standard that allows websites to communicate with users in natural language. This transforms traditional web navigation into conversational experiences. NLWeb was developed by R.V. Guha, a former Google Tech Fellow now at Microsoft.
Model Connectivity Protocol (MCP) Integration
MCP support is now built into Azure and Windows 11. This allows AI models to access and manipulate data across business tools, content repositories, and development environments. MCP servers and clients expose system functions, supporting more advanced agentic workflows.
Windows Subsystem for Linux (WSL) Goes Open Source
Microsoft announced that core components of WSL are now open source under the MIT license, inviting community contributions and improving WSL’s utility for developers running Linux binaries on Windows.
Improved Security and Compliance
The tech giant is embedding security tools like Entra, Defender for Cloud, and Purview directly into Azure AI Foundry and Copilot Studio. The new Entra Agent ID manages Microsoft’s agent identities and selects third-party platforms.
SQL Server 2025 Public Preview
The next version of SQL Server is now in public preview. It features direct AI integration for more intelligent search and built-in vector search capabilities.
AI APIs in Edge Browser
New experimental AI APIs for Microsoft Edge allow developers to leverage on-device models (like Phi 4 mini) for tasks such as math, writing assistance, and translation. These are all processed locally for enhanced privacy and security.
Real-World AI Agent Use Cases
Microsoft also showcased the NFL Combine app, which uses Azure OpenAI Service and AI agents to deliver real-time player analytics via conversational queries.
AI-Powered Weather Forecasting
Microsoft’s Aurora model, running on Azure, delivers ultra-fast, accurate weather predictions. It outperforms leading systems in most benchmarks and demonstrates the power of AI and cloud supercomputing for scientific discovery.
Open Source Initiatives
Along with the WSL, Microsoft also announced plans to open source the GitHub Copilot Chat Extension for VSCode to further support the developer community.
Industry Partnerships and Keynotes
It was a big event from Microsoft, featuring appearances from OpenAI CEO Sam Altman and xAI’s Elon Musk. These highlighted Microsoft’s hosting of Grok 3 and Grok 3 Mini in Azure Foundry. NVIDIA’s Jensen Huang also presented, emphasizing the role of accelerated computing and CUDA in Microsoft’s AI ecosystem.
That’s a wrap for now. These are all the major announcements that the company made during the Build 2025 conference. This makes one thing clear: AI is not a helper anymore; it’s a doer. From Copilot taking on coding tasks independently to MCP and NLWeb turning digital environments into intelligent ecosystems, it’s not about AI assisting anymore.
