How to install WSL on Windows
To install WSL, the Windows Subsystem for Linux, Windows 11 and Windows 10 need just one command and a restart. WSL runs a real Linux, Ubuntu by default, next to Windows: with its terminal, apt and Linux tools, but without a separate virtual machine to set up. This guide covers the install, other distributions, the first user, WSL 1 and WSL 2, and the install errors people search for most.
What you need
- Windows 11, or Windows 10 version 2004 (build 19041) or newer. Type
winverin Start to see yours. - An administrator account on the PC: the install turns on Windows features.
- For WSL 2, virtualization turned on in the BIOS or UEFI. Check it in Task Manager › Performance › CPU: the line Virtualization should say Enabled.
How to install WSL with one command
Right-click Start and choose Terminal (Admin). Run the command and restart Windows when it is done. It turns on the Windows Subsystem for Linux and Virtual Machine Platform features, installs the Linux kernel, makes WSL 2 the default and installs Ubuntu.
wsl --installIf the command only prints the WSL help text, WSL is already on the PC and only a distribution is missing. Install one as shown in the next section.
Choose another Linux distribution
The first command lists the distributions you can install, with names like Ubuntu-24.04, Debian or kali-linux. The second installs the one you name. You can keep several side by side.
wsl --list --online
wsl --install -d Ubuntu-24.04Plain Ubuntu installs the current LTS release. A name with a number, such as Ubuntu-24.04, gives exactly that release. To make another distribution the one wsl opens:
wsl --set-default DebianCreate your Linux user
After the restart Ubuntu opens by itself, or open it from Start. It unpacks for a minute and asks for a User Name and a Password.
- The name has nothing to do with your Windows account. Use lowercase Latin letters, such as
alex. - While you type the password, nothing appears on screen. This is normal. You need it for
sudo, and this user is the Linux administrator. - Each distribution has its own users. A new or reset distribution asks again.
- Forgot the password? In Terminal, open Linux as root:
wsl -u rootThen set a new password, with your user name in place ofalex:passwd alex
Windows doesn’t update the Linux packages. Do it yourself from time to time in the Ubuntu terminal:
sudo apt update
sudo apt upgrade -yWSL 1 or WSL 2: check and switch
The first command lists your distributions and the WSL version each one uses. The second moves a distribution to WSL 2, the third makes WSL 2 the default for new ones. The last one updates WSL itself.
wsl -l -v
wsl --set-version Ubuntu 2
wsl --set-default-version 2
wsl --updateWSL 2 runs a real Linux kernel in a light virtual machine. Everything works there, Docker included, and files inside Linux open fast. WSL 1 needs no virtualization and reads files on the Windows drives faster, but some programs don’t run in it. For development choose WSL 2 and keep projects in your Linux home folder, not in /mnt/c.
Before you stop all distributions and the WSL virtual machine, save your work in Linux: open programs in it are closed. They stop with: wsl --shutdown
If WSL doesn’t install or start
WSL2 is unable to start since virtualization is not enabled on this machine.with the error codeHCS_E_HYPERV_NOT_INSTALLED(current WSL), orError: 0x80370102 The virtual machine could not be started because a required feature is not installed.(older versions): turn on virtualization in the BIOS or UEFI (often named Intel VT-x, AMD-V or SVM) and the Virtual Machine Platform feature, then restart.

- For other errors, install Windows updates and update WSL:
wsl --updateMicrosoft’s troubleshooting page also suggests repairing system files in Terminal as administrator:sfc /scannow
You can also turn on both features with these commands from Microsoft’s manual install page, in Terminal as administrator, then restart:
dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart
dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestartIf you also work on a Mac

Questions and answers
How do I install WSL on Windows 11?
Open Terminal (Admin), run this command and restart: wsl --install Ubuntu opens after the restart and asks you to create a Linux user name and password.
Where are my WSL files in Windows?
In File Explorer under Linux in the left pane, or at \\wsl$\Ubuntu\home\<user>. To open the current folder in File Explorer from the Linux terminal: explorer.exe .
How do I remove a WSL distribution?
This deletes the distribution with all its files, programs and settings, and it can’t be undone, so copy what you need to Windows first. Then run: wsl --unregister Ubuntu WSL itself stays and other distributions keep working.
