No progress on a nix-windows recently. I think the hardest part has just been keeping up with nix when we need to rewrite the build system.
However, https://github.com/NixOS/nix/pull/3160 to switch to Meson, has gotten new life breathed into it. Pamplemousse, who is interning where Edolstra works, is fuzzing Nix and needs Meson to make that less burdensome.
If that does get merged, than nix-windows can just be about Windows and not also be about Nix's build system, which will make it a lot easier to finish.
