Microsoft has released a preview of Windows Subsystem for Linux (WSL), which is now available in the Microsoft Store as a store application exclusively for Windows 11 machines. This means WSL is now decoupled from your Windows version, and you can update it like any other app to get the latest WSL features and improvements.

The company clarified that "this is the exact same WSL that you know and love, all that we’ve changed is where it gets installed and updated from." WSL for Windows 11 will be made generally available for everyone after a testing period of this initial preview.
