Microsoft plans to eliminate all C and C++ code from its products by 2030, as announced by Galen Hunt on November 25, 2025. This decision follows significant malfunctions in Windows 11 that began in July 2025, affecting core components like the Start Menu and Taskbar. The company aims to achieve "1 engineer, 1 month, 1 million lines of code" through AI-assisted rewrites. A patch to address these issues is promised for December 2025. The initiative is part of Microsoft's Future of Scalable Software Engineering group, with a focus on leveraging AI to manage and modify code at scale. A Principal Software Engineer position has been opened, emphasizing expertise in Rust. Microsoft is investing heavily in AI infrastructure, with plans to allocate billions for datacenter construction in 2025.
