Solved Windows Linux System for windows 11 when Upgraded from windows 10

Hi Experts,
I am on win10 and declining the win11 upgrade for some reason esp Windows Linux System ..
Can I retain the WLS2, I installed when I upgrade to win11.
Thank you

Yes WSL 2 requires Windows 10 (x64) Version 1903+, Windows 10 (ARM64) Version 2004, or Windows 11.
Check the documentation from Microsoft here:
and the system requirements are stated here:

@iko22 Thank you but I already have wsl2 on my system should I have to reinstall when I upgrade to win11 ?

Good question. The answer is no you shouldn't have to, but it pays to be prepared in case you do. You should be able to migrate your WSL installation from Windows 10 to a Windows 11 upgrade, without deleting any files.

If you choose a Full Upgrade, then your personal files, drivers, apps, and Windows settings should be retained. WSL on Windows 11 is no longer in Windows Features, it is a App downloaded via the Microsoft Store. The Upgrade should perform the necessary update to install that change.

When upgrading, the Official advice is to verify that your computer meets the minimum requirements, and make a backup of personal data and settings. With WSL that means backing up, or copying, the entire %localappdata%\lxss folder on your Windows 10 computer, then perform the upgrade.
Once upgraded check your WSL installation with wsl --list. If it is not giving what you expect, then perform the following:
2)Install WSL on your new machine (do not create a user account, just control-C out of that prompt).
3)Delete the %localappdata%\lxss directory on your new machine.
4)Copy your saved lxss directory to %localappdata%\lxss
5)run lxrun.exe /setdefaultuser oldusername
6)Launch bash.

Hope that helps!
