WSL2 (Windows Subsystem for Linux 2) runs a true Linux kernel via Hyper-V virtualization.

Read Carefully!

  1. WSL is a system service which requires Admin privileges to install.
  2. A System Reboot is required inbetween install steps.

Cheat Sheet

WSL 2 uses VirtualMachinePlatform and Hyper-V to run a full Linux kernel with 100% syscall compatibility. However, it does not work on all computers and may not work in nested Virtual Machines - such as if running Windows in VirtualBox or Parallels on Mac or Linux.

This will install WSL 1 and WSL 2 ONLY.

Most people want WSL 1 + WSL 2 + Linux.
(WSL 2 is NOT a replacement for WSL 1, it's just another layer of WSL)

How to Install Linux

Once WSL is installed you can download Linux from the Windows Store. We recommend:

How to Switch to WSL 2 Manually

To set WSL 2 for a specific Linux installation:

  1. List all installed Linux versions
    wsl --list --verbose
  2. Set the desired version to WSL 2 with --set-version. For example:
    wsl --set-version Ubuntu-20.04 2

If WSL 2 works on your computer, you may set it as the default:

wsl --set-default-version 2

How to install WSL 2 with PowerShell

If you'd like to install manually, or create your own script, this is how we do it:

# Install WSL 1
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

# Install VirtualMachinePlatform
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

# Download and Install the WSL 2 Update (contains Microsoft Linux kernel)
& curl.exe -f -o wsl_update_x64.msi ""
powershell -Command "Start-Process msiexec -Wait -ArgumentList '/a ""wsl_update_x64.msi"" /quiet /qn TARGETDIR=""C:\Temp""'"
Copy-Item -Path "$env:TEMP\System32\lxss" -Destination "C:\System32" -Recurse

# Also install the WSL 2 update with a normal full install
powershell -Command "Start-Process msiexec -Wait -ArgumentList '/i','wsl_update_x64.msi','/quiet','/qn'"

Error: Required Feature Not Installed

Installing, this may take a few minutes...

Error: 0xXXXXXXXX The virtual machine could not be started because a required feature is not installed.

It may be that your computer does not support virtualization because:

  • it lacks hardware support in the CPU for VTx
  • VTx is disabled in the BIOS or EFI
  • Virtualization has disabled in Windows 10

You should switch back to WSL 1 until you solve this problem:

wsl --set-default-version 1
wsl --list --verbose
wsl --set-version Ubuntu-20.04 1

Error: Nested Virtual Machines

WSL2 may not work properly if you are already running Windows inside of a Virtual Machine, especially if MacOS or Linux is the VM Host.
