Microsoft aims to replace its C and C++ codebase with Rust by 2030, leveraging AI to automate the translation process. They're hiring engineers to develop tools for this extensive project, which is part of a broader effort to improve software security and reduce technical debt. However, a recent update clarifies that this initiative is a research project, not a direct rewrite of Windows.

Anthropic and Microsoft have expanded their partnership, making Claude Sonnet 4.5, Haiku 4.5, and Opus 4.1 available in public preview on Microsoft Foundry. This integration allows developers to use Claude for coding, agent development, and office tasks while streamlining procurement processes within the Microsoft ecosystem.
