Microsoft makes it official: Dark mode is getting a major (and sorely needed) upgrade on Windows 11
Windows Central

It's widely known at this point that Windows 11's dark mode is woefully incomplete. In fact, dark mode on Windows has been unfinished for the better part of a decade, with various areas of the system still without consistent dark mode support in commonly viewed UI surfaces such as copy dialogs and file popups to this day.

Luckily, it seems that won't be the case much longer. Microsoft has now confirmed that it's working on adding dark mode to more areas of the Windows 11 interface, starting with prominent areas of the File Explorer and other legacy popup windows like the Run dialog.
