How to Fix Dark Theme File Explorer Not Working in Windows 11: Step-by-Step Solutions

Many Windows 11 users enjoy using the dark theme for File Explorer because it is easier on the eyes, especially in low-light conditions. However, sometimes the dark theme may not work as expected, leaving File Explorer stuck in the light mode. This issue can cause frustration, but the good news is that it can usually be fixed with some simple steps.

In this guide, we will walk you through easy and detailed solutions to get the dark theme working again in File Explorer on Windows 11. Each step is explained clearly so even beginners can follow along without trouble.

Before diving into the fixes, it’s helpful to understand why the dark theme might not apply properly. It can be due to incorrect settings, system glitches, or outdated software components.

Let’s explore the step-by-step solutions to bring back the dark theme for your File Explorer.

Quick Note: Prerequisites and Initial Checks

Before starting the troubleshooting, make sure of the following:

  • Windows 11 is updated: Ensure your system has the latest updates installed. Windows updates often fix bugs related to themes.
  • Dark mode is enabled system-wide: The dark theme in File Explorer depends on your system theme settings.
  • Restart File Explorer: Sometimes, a simple restart of the File Explorer process can resolve minor glitches.

Step 1: Verify Dark Mode is Enabled in Settings

The dark theme for File Explorer follows the system’s app mode setting. If this is not enabled, File Explorer will stay in light mode.

  1. Click on the Start button and select Settings (gear icon).
  2. Go to Personalization from the left side menu.
  3. Select Colors.
  4. Under the “Choose your mode” dropdown, select Dark.
  5. Scroll down and ensure the option “Choose your default Windows mode” is also set to Dark.

This sets the entire system, including File Explorer, to dark mode. If this is already set and File Explorer is still not dark, move to the next step.

Step 2: Restart File Explorer Process

Sometimes File Explorer needs a refresh to apply theme changes. Restarting it can help.

  1. Right-click on the Taskbar and select Task Manager.
  2. In the list of processes, find Windows Explorer.
  3. Right-click on it and choose Restart.

This will refresh File Explorer without needing to reboot your entire computer.

Step 3: Check for Conflicting Third-party Themes or Apps

Some third-party customization apps or themes may interfere with Windows’ native dark mode.

  • Uninstall or disable any third-party theme apps temporarily.
  • Restart your computer and see if File Explorer switches to dark mode.

If File Explorer works fine after this, the issue is likely caused by those apps.

Step 4: Run System File Checker (SFC) Scan

Corrupted system files can cause theme issues. Running the System File Checker tool helps repair these files.

  1. Press Windows + S and type cmd.
  2. Right-click on Command Prompt and select Run as administrator.
  3. In the Command Prompt window, type the following command and press Enter:
sfc /scannow

This scan will check for missing or corrupted system files and fix them automatically. After it finishes, restart your PC and check File Explorer again.

Step 5: Use Windows Registry Editor to Force Dark Mode

If the problem persists, you can manually enable dark mode for File Explorer through the Windows Registry. Be very careful when editing the registry, as incorrect changes can affect your system.

  1. Press Windows + R to open the Run dialog.
  2. Type regedit and press Enter to open the Registry Editor.
  3. Navigate to the following path:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionThemesPersonalize
  1. Look for the value named SystemUsesLightTheme.
  2. Double-click it and change the value data from 1 to 0.
  3. Close Registry Editor and restart your computer.

This forces Windows to apply the dark theme to system apps including File Explorer.

Alternative Method: Use Windows Terminal to Change Theme

For advanced users, you can also change the theme using a PowerShell command instead of editing the registry manually.

  1. Right-click the Start button and select Windows Terminal (Admin).
  2. Run the following command:
Set-ItemProperty -Path "HKLM:SOFTWAREMicrosoftWindowsCurrentVersionThemesPersonalize" -Name "SystemUsesLightTheme" -Value 0

Restart your PC after running this command to see the changes.
