Two Windows recovery and deployment DLLs have shipped Rust since the first 24H2 build and are now 96 percent Rust by the linker's own accounting. A census of 13,988 live files and 44,889 more in the component store on one Windows 11 25H2 installation, with Microsoft's public symbol files used to measure how much of each binary rustc produced, and 83 GPU driver matches explained by LLVM rather than Rust. Hashes, symbol tables and the full census attached.
