I got issues open with omni and talos to add manifest properties to the Windows executables. The primary place to change in my proof of concept is in the Dockerfile. Since that Dockerfile is generated by kres, the kres executable needs updated with the relevant lines. I already got a branch with a kres update that it did indeed output the desired lines, but I gotta refine it more.
See also the issue for omnictl: siderolabs/omni#666
See also the issue for talosctl: siderolabs/talos#9429
See also https://github.com/siderolabs/omni/pull/667/commits for the omnictl POC which manually edits Dockerfile so far
Draft change so far for kres for this: #451
