Windows 11 Insider Preview Build 25905 - Rust in the Windows Kernel

Rust offers advantages in reliability and security over traditional programs written in C/C++. This preview shipped with an early implementation of critical kernel features in safe Rust. Specifically, win32kbase_rs.sys contains a new implementation of GDI region. While this is a small trial, we will continue to increase the usage of Rust in the kernel. Stay tuned!
