How to Change Copilot Theme in Windows 11
The Copilot theme in Windows 11 changes the look of Microsoft’s built-in AI assistant between dark, light, and system color modes to match your desktop style. Copilot is a desktop helper that answers questions and changes PC settings through typed or spoken requests.
Microsoft added these theme options after the Windows 11 version 23H2 update to help the floating AI window fit in with your desktop style. Open the settings menu inside the app to pick a look that works best for your screen.
Click your profile picture or the menu icon in the Copilot app’s top right corner, then select Appearance. Choose your preferred theme from Light, Dark, or System default to instantly update Copilot’s colors and background.
Why change the theme?
Tailoring interface colors helps reduce eye strain during long sessions. Dark mode works better for low-light rooms, while brighter palettes improve readability in daytime conditions. Matching the assistant to the main operating system appearance keeps the desktop looking cohesive.
What happens when you change the theme?
Selecting a new visual style forces the Copilot window to instantly update its colors and background to match the chosen preference. This adjustment makes the interface far more comfortable to view.
