Windows Subsystem for Linux (WSL) is a feature of Windows that allows you to run a Linux environment on your Windows machine, without the need for a separate virtual machine or dual booting. 

WSL is designed to provide a seamless and productive experience for developers who want to use both Windows and Linux at the same time**.

WSL 2 is the default distro type when installing a Linux distribution.WSL 2 uses virtualization technology to run a Linux kernel inside of a lightweight utility virtual machine (VM).Linux distributions run as isolated containers inside of the WSL 2 managed VM.
