In Windows 11 you won't have a system tray either, if any of its essential Services are disabled or encumbered:

Capability Access Manager Service

Network List Service

Network Store Interface Service

Even if you enable ShowSystrayDateTimeValueName and SystemTrayChevronVisibility in the registry, you also need those 3 "unrelated" services running which more or less substitute for systray.exe.

Of course you need Network Store Interface anyway, regardless if you are not networking or using any "Store Apps", or your display may be so faulty the PC might not even fully boot.

Progress in this direction never stops :\

Surely you have those registry keys incorrect, it's not called the systray!
