Enable Dark Theme in File Explorer in Windows 10

As you may already know, Microsoft is going to add a new dark theme to File Explorer in Windows 10. It can already be activated in Windows 10 Build 17650, which was recently released to Skip Ahead insiders. If you would like to enable it right now and see the work in progress, here's how it can be done.

Microsoft has added the dark theme to the classic desktop app File Explorer in Windows 10 "Redstone 5". Recent builds of the OS incude the dark theme for File Explorer which can be enabled in the Settings app. Here is how it looks:

Windows 10 Enable File Explorer Dark Theme

Enabling dark mode in File Explorer is possible using an option in the Settings app, which switches the app theme under Personalization -> Color. Unlike many Store (UWP) apps, File Explorer hasn't a dedicated option to turn on the dark theme separately from Settings. It follows the global option. Many of the first-party apps in Windows 10 follow the system option or have their own options for enabling the dark theme.

To enable the dark theme in File Explorer in Windows 10, do the following.

  1. Open the Settings app.
  2. Go to Personalization -> Colors:
  3. Scroll down to the bottom of the page to the option "Choose your default app mode". There, turn on the Dark option to activate the appropriate color scheme.Windows 10 Enable Dark Mode
  4. The dark theme is now enabled.

In older pre-release builds of Windows 10 the dark theme was locked. The instructions below could be used to unlock it using a third-party tool Mach2.

Enable Dark Theme in File Explorer in Windows 10

  1. Ensure that you have Windows 10 Build 17650 installed. Refer to the article How to find the Windows 10 build number you are running.
  2. Download the mach2 tool. Use the following links: mach 2 for Windows 10 64-bit | mach2 for Windows 10 32-bit
    To find which version you need, see the article How to determine if you are running 32-bit Windows or 64-bit. Also, you can find the actual version of mach2 on the "releases" tab on GitHub.
  3. Extract the ZIP archive to any folder you want. For example, you can extract it to the folder c:\mach2.Windows 10 Mach2 Archive
  4. Go to that folder with File Explorer.Windows 10 Mach2 Extracted
  5. Type cmd.exe in the address bar of File Explorer and hit the Enter key.Windows 10 Type Cmd In The Address Bar
  6. A new command prompt window will open. Type the following command: mach2 enable 10397285.Enable Dark Theme File Explorer Windows 10
  7. Restart Windows 10.

You are done!

To activate the theme,

  1. Open Settings.
  2. Navigate to Personalization -> Colors.
  3. On the right, select the option Dark under Choose your default app mode.Windows 10 Enable Dark Mode

I hope this will save you some time.

The reason I wrote this post is because some readers are a little bit confused with GitHub and the command prompt, so I decided to cover the procedure in detail.

        what exactly you too?
        Install the most recent RS5 build, it doesn’t require any manual editing. Everything works out of the box.
