How to Fix Windows Subsystem for Linux Optional Component Not Enabled Error on Windows 11

If you are trying to use the Windows Subsystem for Linux (WSL) on your Windows 11 computer and see an error saying the optional component is not enabled, don’t worry. This issue is common and can be fixed with a few simple steps. WSL allows you to run Linux distributions directly on Windows without the need for a virtual machine.

In this article, we will guide you through the process of enabling the Windows Subsystem for Linux optional component correctly. Each step is explained in detail to help even beginners fix the error easily. By following these instructions, you can get WSL up and running smoothly on your system.

Whether you are installing WSL for the first time or troubleshooting an existing setup, these steps will cover all the basics and some advanced tips. Let’s get started and fix this error quickly.

This guide is designed to be straightforward, so take your time and follow each step carefully.

Quick Note: Prerequisites and Checks Before You Begin

  • Windows 11 Version: Ensure your Windows 11 is updated to at least build 22000 or later. WSL works best on newer versions.
  • Administrator Access: You need to have administrator privileges on your PC to enable optional Windows features.
  • Internet Connection: A stable internet connection is important if you need to download Linux distributions or updates.
  • Restart Ready: Some steps will require you to restart your computer to apply changes.

Step 1: Enable Windows Subsystem for Linux Using Settings

The easiest way to enable WSL is through the Windows Features menu. This built-in tool lets you turn Windows components on or off.

  1. Press Windows + S to open the search bar.
  2. Type “Turn Windows features on or off” and click the matching result.
  3. In the Windows Features window, scroll down and look for “Windows Subsystem for Linux”.
  4. Check the box next to it. If you also want to use the latest WSL 2 features, check “Virtual Machine Platform” as well.
  5. Click OK and wait for Windows to apply the changes.
  6. Restart your computer when prompted to complete the installation.

Why this step is important: Enabling WSL through Windows Features activates the underlying system components needed to run Linux distributions. Without this, WSL cannot function.

Step 2: Use PowerShell to Enable WSL (Alternative Method)

If you prefer using commands or the Settings method did not work, you can enable WSL via PowerShell. This can sometimes bypass interface glitches.

  1. Right-click the Start button and select Windows Terminal (Admin) or PowerShell (Admin).
  2. In the terminal window, type the following command and press Enter:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
  1. Next, enable the Virtual Machine Platform with this command:
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
  1. Restart your computer to apply these changes.

Why use PowerShell? Sometimes, Windows Features UI does not register changes properly. PowerShell commands directly modify system components, offering a more reliable way to enable WSL.

Step 3: Set WSL Version to 2 (Recommended)

WSL 2 offers better performance and full Linux kernel support. After enabling WSL, you should set it as the default version.

  1. Open Windows Terminal (Admin) or PowerShell as administrator.
  2. Run this command:
wsl --set-default-version 2

This command tells Windows to use WSL 2 for any new Linux installation.

Note: If you get an error about the kernel update, visit the official Microsoft page to download and install the latest WSL 2 Linux kernel update package.

Step 4: Install a Linux Distribution

Once WSL is enabled, you can install your favorite Linux distribution from the Microsoft Store.

  1. Open the Microsoft Store app.
  2. Search for “Linux” or a specific distribution like Ubuntu, Debian, or Fedora.
  3. Select the distribution you want and click Install.
  4. After installation, click Launch to complete the initial setup.

Now you should be able to run Linux commands directly on Windows.

Advanced Option: Manually Enable WSL Using Command Prompt

If PowerShell commands fail, you can also try enabling WSL using the Command Prompt with administrative rights.

  1. Open Command Prompt (Admin).
  2. Type the following commands one by one and press Enter after each:
dism /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Restart your PC to apply changes.

When Nothing Works: Final Options

If you still face issues after trying all the above steps, consider the following:

  • Check for Windows Updates: Sometimes, missing updates can cause WSL issues. Go to Settings > Windows Update and install all pending updates.
  • Reset WSL: You can reset WSL by uninstalling and reinstalling the Linux distributions or using wsl --unregister <distro_name> in PowerShell.
  • Use the Official Microsoft WSL Documentation: Visit Microsoft’s WSL official documentation for advanced troubleshooting guides.
