How to turn on dark mode on Windows 11

2 min read · 4 steps · Updated 2 October 2026

Short answer

Open Settings, choose Personalisation, then Colours, and set Choose your mode to Dark. Windows, the taskbar and most apps switch to a dark background.

Dark mode shows light text on a dark background. Many people find it more comfortable in the evening, and on laptops with OLED screens it saves some battery.

These steps are for Windows 11. The pictures are simplified diagrams of the Settings window, not screenshots, so colours and spacing on your PC look a little different.

    Set Choose your mode to Dark

    Open the menu on the right and pick Dark. The change is immediate.

  4. Or mix the two with Custom

    Choose Custom to set Windows itself, meaning the taskbar and Start menu, and your apps separately. A dark taskbar with light apps is a popular mix.

Good to know

Websites follow this setting only if they support it. In Edge or Chrome you can set the appearance to Dark in the browser's own settings as well.

Office apps have their own setting: File, Account, Office Theme.

Dark mode does not reduce blue light. For that, use Night light: how to turn on Night light.

In short: Settings, Personalisation, Colours, Choose your mode, Dark.
