In a sweeping overhaul of its core technologies, Microsoft announced plans to replace its reliance on C/C++ with the newer programming language Rust by 2030. The move, driven by increasing cybersecurity concerns and a demand for more memory-safe code, impacts not only the Windows operating system but a wide range of Microsoft products [[2]]. This transition represents a notable industry shift as Rust gains prominence for its security features and performance [[3]], although setting up a Rust development environment on Windows can present initial hurdles [[1]].
Microsoft Plans to Replace C/C++ with Rust by 2030
Microsoft intends to transition its core Windows codebase, and other programming languages, to Rust by 2030, the company announced. This move signals a significant shift in Microsoft’s development strategy, prioritizing memory safety and security in its foundational software.
The company aims to completely replace C/C++ with Rust over the next seven years. According to the announcement, this transition will encompass not only Windows itself but also other codebases currently reliant on the older languages. The decision reflects a growing industry trend toward adopting Rust, known for its robust safety features and performance capabilities.
“We are committed to building a more secure and reliable future for our customers,” a Microsoft spokesperson stated. “Rust provides the tools and features necessary to achieve this goal.”
The transition to Rust is expected to be a complex and lengthy process, requiring substantial investment in developer training and code refactoring. However, Microsoft believes the long-term benefits – including reduced vulnerabilities and improved system stability – will outweigh the initial costs. The move comes as cybersecurity threats continue to escalate, placing increased pressure on software developers to prioritize security.
Microsoft has already begun incorporating Rust into some of its projects, and the company plans to accelerate this adoption in the coming years. The 2030 deadline represents a firm commitment to a future where Rust plays a central role in the Microsoft ecosystem.
