Dark mode has always been a "half-finished product" on the Windows desktop version. Even after Windows 10 was launched and support ended, Windows' dark mode experience is still imperfect.For example, although core components such as File Explorer have received dark mode support, it is only a surface-level implementation. As long as you enter any old menu or dialog box, Windows will immediately "throw a flash bomb" - the sudden white interface is extremely glaring and lacks visual consistency.

However, after years of waiting, Microsoft has finally begun to move in the right direction. The recent Windows 11 update has more user interfaces, especially those classic and old interfaces, and adds dark mode support:
run dialog
Folder options
Common file operations (such as copy/move)

These key improvements make the operating system more comfortable to use at night and the overall vision more consistent. These dark mode improvements have been rolled out to the Dev and Beta channels of Windows Insiders and are still being gradually pushed.
There is also the function of automatically switching themes on a schedule. Although it is not directly integrated into the settings, Microsoft has implemented the automatic theme switching function through the latest PowerToys.
