Fix The Operation Could Not Be Started Because a Required Feature Is Not Installed: WSL

The Windows Subsystem for Linux (WSL) is a powerful tool that lets you run Linux distributions like Ubuntu, Debian, or Kali directly on Windows. However, you might run into errors during installation or when running a distro, such as:

“The operation could not be started because a required feature is not installed. Error code: Wsl/InstallDistro/Service/RegisterDistro/CreateVm/HCS/HCS_E_SERVICE_NOT_AVAILABLE.”

This error typically occurs when trying to install or run a WSL distro, indicating that a critical component, like the Virtual Machine Platform or Hyper-V, is missing or misconfigured. Don’t worry—this comprehensive guide will walk you through why this error happens, how to fix it, and how to prevent it in 2025. With clear steps and beginner-friendly explanations, you’ll have WSL up and running in no time.

What Causes the WSL HCS_E_SERVICE_NOT_AVAILABLE Error?

Before diving into solutions, let’s understand why this error occurs. The error code Wsl/InstallDistro/Service/RegisterDistro/CreateVm/HCS/HCS_E_SERVICE_NOT_AVAILABLE points to issues with the Hyper-V Compute Service (HCS) or related virtualization components. WSL2, the default version of WSL in 2025, relies on virtualization to create a lightweight virtual machine (VM) for running Linux distributions. If the required features aren’t enabled or configured correctly, WSL can’t proceed.

Common Causes

• Virtual Machine Platform Disabled: WSL2 requires the Virtual Machine Platform feature, which may not be enabled.
• Hyper-V Issues: Some Hyper-V components, like the Hyper-V Host Compute Service (vmcompute.exe), may be disabled or missing.
• BIOS Virtualization Disabled: Virtualization extensions (e.g., Intel VT-x or AMD-V) must be enabled in your BIOS/UEFI.
• Windows Version Incompatibility: Older Windows builds or Home editions may lack full Hyper-V support.
• Corrupted WSL Installation: A faulty WSL or distro installation can cause configuration errors.
• Windows Updates: Recent updates might disable or conflict with WSL components.
• Third-Party Software Conflicts: Antivirus or other virtualization software (e.g., VirtualBox) can interfere with WSL.

Step-by-Step Fixes for the WSL Error

Below are proven solutions to resolve the HCS_E_SERVICE_NOT_AVAILABLE error, based on user reports and Microsoft’s official troubleshooting guides. Follow these steps in order, testing WSL after each one.

Step 1: Enable Required Windows Features

WSL2 requires specific Windows features to function. Let’s ensure they’re enabled.

1. Open Windows Features:

• Press Win + S, type Turn Windows features on or off, and select it.

1. Enable Key Features:

• Check the boxes for:
  • Windows Subsystem for Linux
  • Virtual Machine Platform
  • Windows Hypervisor Platform (optional, but recommended for WSL2)
• If Hyper-V is available (not on Windows 11 Home), enable it.

1. Save and Restart:

• Click OK and restart your PC when prompted.

Note: If these features are already enabled, try disabling them, restarting, then re-enabling and restarting again. This can reset configurations.

Step 2: Verify Virtualization in BIOS/UEFI

WSL2 requires CPU virtualization support (Intel VT-x, AMD-V, or SVM) enabled in your BIOS.

1. Check Virtualization Status:

• Open Task Manager (Ctrl + Shift + Esc), go to the Performance tab, and check if Virtualization says Enabled. If not, proceed to BIOS.

1. Enter BIOS/UEFI:

• Restart your PC and press the key to enter BIOS (usually F2, Del, or Esc—check your manufacturer’s guide).

1. Enable Virtualization:

• Look for settings like Intel VT-x, AMD-V, SVM Mode, or Virtualization Technology and enable them.
• Save changes (usually F10) and restart.

1. Verify in Windows:

• In an elevated PowerShell (Run as Administrator), run:
  powershell systeminfo | findstr -i "Hyper-V Requirements"
• Ensure Virtualization Enabled in Firmware says Yes.

Pro Tip: If virtualization is disabled, you may need to update your BIOS firmware. Check your manufacturer’s website for instructions.

Step 3: Update WSL and Install the Linux Kernel

An outdated WSL or missing kernel can cause errors.

1. Update WSL:

• Open PowerShell as Administrator and run:
  powershell wsl --update
• This ensures you have the latest WSL version (e.g., 2.1.5.0 or higher in 2025).

1. Install Linux Kernel Update:

• If the error persists, download and install the latest WSL2 Linux kernel update from Microsoft’s WSL2 kernel page.

1. Check WSL Version:

• Run:
  powershell wsl --version
• Confirm you’re on WSL2 and the latest kernel (e.g., 5.15 or newer).

Step 4: Check Hyper-V Host Compute Service

The vmcompute.exe service is critical for WSL2. If it’s disabled or missing, you’ll see the HCS error.

1. Open Services:

• Press Win + R, type services.msc, and press Enter.

1. Find Hyper-V Host Compute Service:

• Locate Hyper-V Host Compute Service in the list.
• Ensure it’s set to Automatic and running. If not:
  • Right-click, select Properties, set Startup type to Automatic, and click Start.

1. Start via PowerShell (if needed):

• In an elevated PowerShell, run:
  powershell net start vmcompute
• If you get an error like “The service name is invalid,” proceed to the next step.

Step 5: Reinstall WSL and the Distro

A corrupted WSL or distro installation can cause the error. Let’s reinstall.

1. Uninstall the Distro:

• Open PowerShell as Administrator and list installed distros:
  powershell wsl --list --all
• Unregister the problematic distro (e.g., Ubuntu):
  powershell wsl --unregister Ubuntu

1. Uninstall WSL:

• Go to Turn Windows features on or off, uncheck Windows Subsystem for Linux and Virtual Machine Platform, and restart.

1. Reinstall WSL:

• Run in PowerShell as Administrator:
  powershell wsl --install
• This reinstalls WSL and downloads a default distro (usually Ubuntu).

1. Install a Specific Distro:

• Open the Microsoft Store, search for your preferred distro (e.g., Ubuntu 22.04), and install it. Alternatively, use:
  powershell wsl --install -d <DistroName>
  (e.g., wsl --install -d Ubuntu-22.04).

Step 6: Check for Windows Updates

Outdated Windows builds can cause compatibility issues.

1. Check for Updates:

• Go to Settings > Windows Update > Check for updates.
• Install all available updates, especially those related to WSL or Hyper-V.

1. Verify Build:

• Run in PowerShell:
  powershell winver
• Ensure you’re on Windows 10/11 build 18362 or later.

Step 7: Enable Hypervisor Launch Type

If the hypervisor is disabled, WSL2 won’t work.

1. Check Hypervisor Status:

• In an elevated PowerShell, run:
  powershell bcdedit /enum | findstr -i hypervisorlaunchtype
• If it says Off, enable it:
  powershell bcdedit /set hypervisorlaunchtype Auto

1. Restart:

• Reboot your PC and try running WSL again.

Step 8: Resolve Software Conflicts

Third-party software like VirtualBox or antivirus programs can interfere with WSL2.

1. Check for Conflicting Software:

• Temporarily disable antivirus or add exceptions for WSL-related files (e.g., vmcompute.exe).
• If using VirtualBox, ensure it’s updated to a WSL2-compatible version (7.0 or later).

1. Use Autoruns:

• Download Autoruns to identify and disable suspicious startup items that might interfere with WSL.

1. Switch to Bridged Networking (if applicable):

• If network-related errors persist, edit or create a .wslconfig file in C:\Users\<YourUsername>:
  plaintext

[wsl2]

networkingMode=bridged vmSwitch=wsl_switch Create a virtual switch named wsl_switch in Hyper-V Manager > Virtual Switch Manager > External.

Step 9: Reset WSL Configuration

If the error persists, reset WSL to clear configuration issues.

1. Reset WSL:

• In PowerShell as Administrator, run:
  powershell dism.exe /online /disable-feature /featurename:VirtualMachinePlatform /norestart dism.exe /online /disable-feature /featurename:Microsoft-Windows-Subsystem-Linux /norestart
• Restart your PC.
• Re-enable the features:
  powershell dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
• Restart again.

1. Check Distro Folder:

• Ensure the distro’s folder (e.g., C:\Users\<YourUsername>\AppData\Local\Packages\CanonicalGroupLimited...) isn’t compressed or encrypted:
  • Right-click the folder, select Properties > Advanced, and uncheck Compress contents and Encrypt contents.
• Restart and try launching the distro.

Step 10: Advanced Troubleshooting

If none of the above work, try these advanced steps:
