Adding dark mode for current Windows 10/11 builds, was already several month of work. I don't do this for deprecated windows versions.
As for your mistakes:
1) It now longer loads ADK, if the current windows don't needed it.
2) Version display was removed, because some people carelessly updated and just broke supported OS versions, for no reason.
3) That's wanted, looking more current system conform.
Re-uploaded, you now can disable these 3 options in WinNTSetup.ini.
