“If you’re on the Win11 Insider ring, you’re getting the first taste of Rust in the Windows kernel,”
Microsoft announced Rust in the Windows kernel in mid-April and Mark Russinovich says it already ships in an Insider build. Nobody will say which Insider channel. David Weston calls memory safety a key source of exploits, which is Microsoft admitting decades of C in the kernel built its Patch Tuesday business. A few Rust modules in a kernel of that size is a press release, not a rewrite.
