WM_NIGHT is a tray app that paints Windows' leftover light-mode corners dark. The OS shipped a dark theme years ago but never finished the job: regedit, the Control Panel, and a long tail of classic dialogs still blast you with white. WM_NIGHT injects umbra's dark-mode engine into those processes and themes them at the source.
It themes Explorer and regedit near-perfectly and the Control Panel reasonably well, and you can add any leftover Win32 app to a registry whitelist. A signed build launched from a trusted location keeps uiAccess, so it can also theme elevated windows (an elevated regedit or mmc) without itself running elevated.
