    Which - if any - of Microsoft's operating systems have signed operating
    system files, so that it becomes next to impossible for a rootkit or trojan
    to interfere with the core OS files? I would like to know about the
    consumer as well as server operating systems.

    Doesn't matter for a rootkit. Signing is irrelevant since the rootkit
    loads before the OS loads (or hides itself from normal visibility in the
    file system after the OS loads by stacking its handler in the file API).
    No general-purpose OS can prevent itself from getting infected. They
    don't need to replace any OS files but that has certainly happened.
