Microsoft aims to eliminate C and C++ code from Windows products by 2030, leveraging AI-assisted rewrites. This announcement follows Windows 11 malfunctions starting in July 2025, affecting core components like the Start Menu and Taskbar. Microsoft promised a December 2025 patch to address these issues.
Malfunctions and Immediate Actions
The Windows 11 failures were linked to XAML components, causing widespread disruption. Microsoft recommended temporary fixes, including app resets and update rollbacks, while preparing a comprehensive patch.
Galen Hunt, a distinguished engineer at Microsoft, described an algorithmic infrastructure using AI to modify code at scale. The initiative is part of Microsoft CoreAI's Future of Scalable Software Engineering group.
Transition to Rust
In a shift away from C and C++, Microsoft seeks engineers with Rust experience for systems-level work. Rust's memory safety is a primary motivator for this transition.
- Microsoft announced a push for AI-assisted code rewrites by 2030.
- Windows 11 issues began in July 2025; patch promised by December 2025.
- The switch to Rust aims to improve code reliability and security.
- Industry concerns focus on AI-generated code testing and quality.
- Microsoft has not detailed the timeline for AI-generated Rust code deployment.
Challenges and Industry Concerns
The initiative has prompted skepticism about AI's capacity to generate correct Rust code at scale. Concerns center on testing and potential errors in AI-generated outputs. Microsoft has invested in AI infrastructure but has not shared its testing methods or deployment timeline.
The upcoming December patch will be a critical test for resolving Windows 11's technical issues. Meanwhile, the transition to AI-generated Rust code remains a longer-term objective, with extensive validation needed before deployment.
