I noticed the other morning that they’ve either re-written or are growing the win32k driver in rust. This was either in Server ‘25 or vNext though I can’t remember.

Given win32k implements a good chunk of the kernel-mode graphics and windowing system it’s a pretty good place to start that effort.

edit: win32kbase_rs.sys was what it was called, and I’m pretty sure it was 2025 I pulled it from but it might be on earlier versions too
