Dark mode changes Windows menus, Settings, File Explorer, and supported apps from bright backgrounds to a darker theme. It can be easier at night and may save some power on OLED screens.
This applies to Windows 10 and Windows 11.
Does This Affect You?
Use Windows dark mode for the system interface, then check individual apps if browsers, Office, or older desktop programs do not follow the system theme.
Turn On Dark Mode
- Open Settings > Personalization > Colors.
- Under Choose your mode, select Dark.
- Windows applies the theme immediately.
Use Custom Mode
- On the same Colors page, choose Custom.
- Set the default Windows mode for the taskbar, Start menu, and Settings.
- Set the default app mode for apps that follow the system theme.
- Choose any light/dark combination you prefer.
Automatic Switching
Some Windows 11 builds expose related theme or night-light scheduling, but automatic light/dark switching is not consistent across every version. If your PC does not include it, a trusted Microsoft Store tool such as Auto Dark Mode can switch themes by schedule or sunset/sunrise.
Dark Mode Notes
Some Apps Need Their Own Toggle
Chrome, Edge, Firefox, Microsoft Office, and many third-party apps may have separate theme controls in their own settings.
File Explorer Follows App Mode
If File Explorer stays light, make sure the default app mode is set to Dark, not only the Windows mode.
Older Apps May Not Support It
Classic desktop programs must implement dark themes themselves; Windows cannot force every old interface to become dark cleanly.
Return to Light Mode
Go back to Colors and choose Light.
