I heard that the recent Windows 10 Anniversary Update will come with a optional dark theme
I would like to know whether this "Dark Theme" is really a theme, a theme that will affect the light resources of the user interface as the white Explorer's background too, or is just the same "hidden" theming feature seen in previoues Windows 10 versions that just will change to dark the Universal Apps and other minor things.
Note: I'm not asking for 3rd party themes, please focus only on the question I did.
