Microsoft puts the brakes on speculation about a full Rust port of Windows

Microsoft has clarified that its initiative to explore migrating C and C++ codebases to Rust is primarily a research project, not a definitive plan to rewrite Windows in Rust by 2030. The company has been integrating Rust into specific areas of its operations, particularly in newer versions of Windows 11, to enhance security without overhauling existing systems. Microsoft has incorporated certain components of the Windows kernel in Rust but has not announced plans for a full migration of all kernel and user-space components. The project aims to develop tools for efficient analysis and partial automation of transferring large codebases to other programming languages, with AI-supported processes involved. Assertions that this research will lead to a complete Rust version of Windows are unsubstantiated.

Microsoft engineer clarifies post on eliminating C, C++ languages: Windows is…

A Microsoft distinguished engineer, Galen Hunt, clarified that a project aimed at rewriting parts of Microsoft's code using AI and Rust is strictly research-focused and not an official plan to phase out C and C++ from Windows by 2030. His team is developing technology for large-scale code migration between programming languages, aiming for "1 engineer, 1 month, 1 million lines of code." This project is part of Microsoft's Future of Scalable Software Engineering group and is not a roadmap for Windows 11 or future versions. Microsoft has been integrating Rust into its products, including rewriting segments of the Windows kernel in 2023, as part of its commitment to adopting memory-safe programming languages.

Microsoft engineer clarifies post on eliminating C, C++ languages: Windows is…

A Microsoft engineer, Galen Hunt, clarified that his earlier statements about phasing out all C and C++ code by 2030 were misinterpreted. He emphasized that the initiative he discussed is a research project focused on developing technology for large-scale code migration between programming languages, not a definitive plan for Windows. The goal of the project is to enable "1 engineer, 1 month, 1 million lines of code" using AI agents and algorithmic infrastructure. Hunt's team is looking for a Principal Software Engineer with Rust experience to assist in this research. Microsoft has been integrating Rust into its products, including rewriting parts of the Windows kernel in Rust, as it aims to improve security and reduce programming errors. However, Hunt noted that Rust is not necessarily the final destination for all Microsoft code.
