How to Change Task Manager Theme in Windows 11

The Task Manager is a vital tool for monitoring your computer’s health. In Windows 11, this app has received a modern makeover using the WinUI 3 framework and Fluent Design. A key feature of this design is the Mica effect, which makes the window background blend with your desktop wallpaper. Because Task Manager is now a modern app, it follows your system-wide theme settings by default.

Why change the Task Manager theme?

Changing the theme helps reduce eye strain during late-night work sessions. It also allows you to keep your desktop look consistent. Whether you prefer a bright interface or a deep, dark mode, personalizing your tools makes your workflow more comfortable.

What happens when you change it?

When you update the theme, the app immediately switches its color palette. This change is saved locally in your user profile. It does not affect your computer’s performance or speed, as it is purely a visual adjustment.

Global vs. Individual Settings

By default, Task Manager is set to Use system settings. This means if you change your overall Windows 11 theme, Task Manager changes with it.

Troubleshooting UI Glitches

If your Task Manager looks different than the screenshots, ensure you are running Windows 11 22H2 or later. If the theme does not apply, try closing and reopening the app. For persistent issues, check the registry path HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Themes\Personalize to ensure your system theme settings are correctly registered.

Summary

You can easily customize the Task Manager in Windows 11 to suit your visual preferences. By navigating to the settings menu, you can toggle between Light and Dark modes. This ensures your system monitoring tools remain comfortable to view while maintaining the modern Fluent Design aesthetic.
