How to Give Windows 10 a Dark Theme

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.

Edit Themes in the Registry

1. Open the registry editor by hitting Windows + R and typing "regedit" in the run field.

2. Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes by opening the tree in the left side of the window.

3. Create a new key by right clicking in the window pane and selecting New -> Key

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).

6. Name the DWORD "AppsUseLightTheme".

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

8. Navigate to HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Themes\Personalize.

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.

10. Set its value to 0.

11. Close Regedit and reboot your PC.

Your settings menu should now have white text on a black background (as shown below).

4. Select Dark from the theme pulldown.

The Edge menu bar should now be white on black.

Choosing a High Contrast Theme

1. Right click on the desktop and select Personalize.

2. Select Themes from the left pane.

3. Click Theme settings.

4. Select High Contrast #1, High Contrast #2 or High Contast Black.
