A lot of people prefer light text on a dark background, particularly when navigating through menus on their  computers. Some visually-impaired users also find find a "dark" or high-contrast theme much easier to read.
By default, Windows 10's widgets, menus, email client and Edge browser all have black or blue text on a white or gray background. However, by tweaking a few settings, you can give the entire operating system a dark theme.

4. Name the key "Personalize" and open it.

5. Create a new DWORD (32-bit) value by right clicking in the right pane and selecting New > DWORD (32-bit).

7. Set the DWORD's value to 0. To open the DWORD, simply double click on it.

9. Create a new DWORD (32-bit) named "AppsUseLightTheme". As in steps 5 and 6, you create the DWORD by right clicking in the right window pane, selecting New > DWORD (32-bit) and typing in the name.
