In Windows 10, you can turn off the lights for universal apps (I mean you can enable a dark theme through settings) and make every app run in the dark mode. You probably saw a night mode feature in a smartphone app or somewhere in a phone that actually make the light color to dark.

The new dark app mode feature is available if your Windows 10 updated to version 1607. The update was officially arrived in August, 2016 as an Anniversary update and it has lots of new features than all past updates. The new feature comes within this update is a Dark App Mode in the settings menu.

Updating Windows to the new version will also solve many Windows 10 problems.

If you want to check your current Windows 10 version, go to settings > system > about, or type ‘winver’ in Run (Win+R).

You must have version 1607 or above in order to use that dark mode app feature in Windows 10, else you can also try the registry editor hack.

The only official way to change background color of a Windows explorer to dark black is by selecting a high contrast theme from Personalization. By default, Windows has few high contrast themes, in which ‘High Contrast Black’ is the best dark theme.

Right-click over desktop > Personalization > theme > theme settings, and select ‘High Contrast Black’ .

If you don’t like text, hyperlinks and buttons colors, you can customize the coloring your way. Open Run (Win+R), Type ‘control color’ and press the enter button. Here, you can customize the color and appearance of the current theme, such as Windows background color, text color, and title color.
