The Windows Subsystem for Linux (WSL) is a new Windows 10 feature that enables you to run native Linux command-line tools directly on Windows, alongside your traditional Windows desktop and modern store apps.
Starting with Windows 10 build 18836 version 1903, Linux will be added to the navigation pane in File Explorer whenever you enable Windows Subsystem for Linux (WSL).
If you like, you can remove Linux from the navigation without having to disable WSL.
This tutorial will show you how to add or remove Linux in the navigation pane of File Explorer for your account in Windows 10. When you click/tap on the Distro shortcut in Linux, it will show all currently running WSL distros.
