+title: WSL 2 (Hyper-V)
+homepage: https://docs.microsoft.com/en-us/windows/wsl/wsl2-index
+tagline: |
+  WSL2 (Windows Subsystem for Linux 2) runs a true Linux kernel via Hyper-V emulation.
+---
+
+## Cheat Sheet
+
+> WSL 2 uses `VirtualMachinePlatform` and Hyper-V to run a full Linux kernel
+> with 100% syscall compatibility.
+
+After installing WSL and **Rebooting** you will be able to install Linux
+variants from the Windows 10 Store:
+
+- [Ubuntu Linux 20.04](https://www.microsoft.com/store/apps/9n6svws3rx71)
+- [Alpine WSL](https://www.microsoft.com/store/apps/9p804crf0395)
+
+### Admin Privileges Required
+
+It is not possible to install WSL without Admin privileges.
+
+You _will_ need to allow the installer to run as Admin when asked.
+
+### Reboot Required
+
+You will not be able to use WSL without rebooting.
+
+### Switching Between WSL and WSL 2
+
+After rebooting you can set WSL 2 as the default:
+
+```pwsh
+wsl --set-default-version 2
+```
+
+You can list your existing WSL Linuxes:
+
+```pwsh
+wsl --list --verbose
+```
+
+And you can switch between using WSL and WSL 2 without an issues:
+
+```pwsh
+wsl --set-version Ubuntu 2
+```
+
+### Raw PowerShell Install Commands
+
+If you'd like to install manually, or create your own script, this is how we do
+it:
+
+```pwsh
+# 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 WSL Update (contains Microsoft Linux kernel)
+& curl.exe -f -o wsl_update_x64.msi "https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi"
+powershell -Command "Start-Process msiexec -Wait -ArgumentList '/a wsl_update_x64.msi /qb TARGETDIR=""$env:TEMP""'"
+Copy-Item -Path "$env:TEMP\System32\lxss" -Destination "C:\System32" -Recurse
+```
+
+### Nested VMs
+
+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.
