On Windows this module fails to type-check because windows-sys 0.52 defines RegOpenKeyExW/RegQueryValueExW as returning WIN32_ERROR (u32), but these checks compare that u32 to ERROR_SUCCESS as i32. Any Windows build of libdd-common that includes this new module will fail before use; compare against ERROR_SUCCESS without the cast here and in the two RegQueryValueExW status checks.

LGTM FWIW. I found the code confusing, so suggested some more comments.

nit: Do you need is_wow64()? The agent always does KEY_READ_ | KEY_WOW64_64KEY Won't KEY_WOW64_64KEY be a no-op on 64-bit?

Yeah, probably not necessary. I got confused by microsoft doc and claude got defensive

Motivation
We are replicating the agent RC client. One of the thing the agent uses is a stable identity for the agent host, decorrelated from the hostname (as it is not available in som platforms).
It fetches the UUID using a library (psutils), for which there exists no strict equivalent in rust.
This PR adds code that should be feature equal to the agent
