What is secureuxtheme_uninstall() returned 00000000

[RaXorX]

I had to try this because I was having issues with some themes. Clicking on Uninstall and then rebooting, I couldn't apply any themes anymore. Switching to dark/night or day type themes just changed Windows theme to dark and light respectively and the wallpapers/mouse pointers from that theme but not the theme style itself.

So clearly seemed to have uninstalled perhaps. But the weird thing is that after I reinstalled, it's still the same. Reinstalled, rebooted and doesn't work anymore.

Running Windows 11 IoT LTSC 26100.712

But the themes worked when I had done an in-upgrade from Windows 11 Enterprise where secureux was working fine. After the upgrade it was still working fine as well.

Okay, I may have to test on IoT LTSC 24H2 without an in-upgrade but turns out SecureUX isn't working. It's loaded, but not working. Process Hacker shows dll is loaded in winlogon.exe as well.

And it's not just the uninstall, applying the themes as well returns a similar () returned 00000000 at the end of it.
