Advancing Windows for AI Development: Highlights from Build 2025
Microsoft has made significant strides in AI development with exciting new features unveiled at Build 2025. The focus is on enhancing Windows as a robust platform for developers.
What’s New?
One of the standout announcements is the Windows AI Foundry, which evolves the Windows Copilot Runtime. This platform supports the entire AI developer lifecycle, from model selection to deployment.
“We want to democratize the ability for developers to build, experiment and reach users with breakthrough AI experiences.” – Pavan Davuluri
Windows AI Foundry integrates various model catalogs, allowing developers to access ready-to-use open-source models efficiently. This integration simplifies the deployment process across different hardware, including AMD, Intel, NVIDIA, and Qualcomm.
Major Updates
Windows ML serves as the foundation of this AI platform, providing a built-in inferencing runtime. Developers can now deploy their models without needing to package additional runtimes or drivers.
Moreover, new APIs for semantic search and knowledge retrieval are being introduced. These APIs enable developers to create natural language search capabilities within their applications.
Enhanced Security Features
As the threat landscape evolves, Microsoft is also enhancing security. New capabilities like the Virtualization Based Security (VBS) Enclave SDK and post-quantum cryptography (PQC) are now available. These tools will help developers create more secure applications.
What’s Important to Know?
Windows is committed to remaining an open platform. This means developers can expect continuous updates that cater to their needs. The integration of the Model Context Protocol (MCP) will standardize how AI agents interact with native Windows applications.
Additionally, Microsoft is open-sourcing the Windows Subsystem for Linux (WSL). This move invites developers to contribute and customize, making Linux integration smoother within the Windows environment.
“Our north star is clear: to make Windows the best platform for developers, built for this new era of AI.” – Pavan Davuluri
With these updates, Windows is positioning itself as a leader in AI development. The new tools and capabilities will empower developers to innovate and create groundbreaking applications.
Stay tuned for more updates as Microsoft continues to enhance the developer experience on Windows!
