Microsoft Clarifies AI-to-Rust Effort as Research, Not a Windows Rewrite

The group is developing tooling to automate large-scale code translation to cut memory-safety risk.

Overview

  • Galen Hunt’s LinkedIn post outlined a goal to eliminate C and C++ at Microsoft by 2030 and cited a “North Star” of one engineer producing one million lines of code in a month using AI and algorithmic systems.
  • Microsoft’s communications chief told Windows Latest the company has no plans to rewrite Windows 11 in Rust using AI.
  • Hunt updated his post to state that Windows is not being rewritten in Rust with AI and described the work as a research project to enable language-to-language migration within EngHorizons/CoreAI.
  • The team says its infrastructure builds a scalable graph over source code and applies AI agents guided by algorithms to make modifications at scale, with code-understanding components already operating widely.
  • Microsoft is hiring a Principal Software Engineer with production systems-level Rust experience, as the company continues gradual Rust adoption in areas like Windows kernel components and Azure for security and reliability.
