With the July 2021 Windows update installing WSL has become extremely simple, as we will show you.
With the July 2021 and Windows 10 21H1, if you open a PowerShell terminal, you will see the WSL command-line utility is already available, as shown below.
Install a WSL Distribution
To view which Linux distributions are available for install, we run the following command.
wsl --list --online
To install a WSL distribution and effectively enable WSL, we need to run the following command.
wsl --install -d Ubuntu
The above command will install the Ubuntu 20.04 LTS. To install a different distribution, run the following command.
wsl --install --distribution Debian
To complete the installation and use WSL, restart the machine.
