# WSL First open Powershell as administrator and launch the following command: ```powershell dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart ``` This command will install WSL on your computer. After this, you'll need to ==**reboot**==. ## Upgrade to WSL 2 If you're on WSL 1 and want to upgrade to WSL 2, here is the process: 1. Open an elevated powershell and paste the following command: ```powershell dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart ``` 2. Then, enable the Virtual Machine Platform optional feature. ```powershell dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart ``` 3. Now restart your computer to apply these features. Once it's done, open an elevated powershell again and set the default wsl version to 2 ```sh wsl --set-default-version 2 ``` !!! warning "You might see this message after running the command above" WSL 2 requires an update to its kernel component. For information please visit [wsl2kernel](https://aka.ms/wsl2kernel). If you install the MSI from [wsl2kernel](https://aka.ms/wsl2kernel). Once you have the kernel installed, please run `wsl --set-default-version 2` again and it should complete successfully without showing the message. ## Start WSL After reboot, open the microsoft store and install the distribution of your choice, for instance: ==Ubuntu 20.04 lts==. Once it's done, open it and after a few minutes you'll be prompted for the creation of a user account. To make sure it's correctly installed and working, you can open Powershell and paste the following command : ```powershell wsl.exe --list --running ``` Now you should see the name of your distribution in the list. And follow [set_up_your_environment](setup_your_environment.md#install-your-linux-distribution)
