If you want to completely remove the WSL kernel, follow these steps:

In conclusion, removing WSL from Windows 11 is a systematic procedure that respects the layered architecture of modern Windows. It is not a single action but a sequence of termination, unregistration, uninstallation, and verification. Whether motivated by the need to resolve a corrupted kernel or simply to move on from Linux development, following this process ensures that the system remains clean, stable, and free of hidden virtual disk files. As with any system modification, a prudent user will back up important data from within any Linux distribution before issuing the wsl --unregister command—because in the digital realm, as in surgery, precision and preparation are the keys to a successful removal.

To begin, one must address the installed distributions. From an elevated PowerShell or Windows Terminal window, the command wsl --list --verbose reveals all installed distributions along with their current state (e.g., "Running" or "Stopped"). Each distribution must be terminated with wsl --terminate <DistroName> before removal. The command wsl --unregister <DistroName> then performs the irreversible action of deleting the distribution’s ext4 virtual hard disk file (usually stored within the user’s %LOCALAPPDATA%\Packages\ directory) and removing its entry from the Windows bootloader menu. This step is crucial; skipping it leaves behind gigabytes of orphaned data. For users who have installed distributions via the Microsoft Store, unregistering them is sufficient, though the Store listing itself will still show "Installed" until explicitly removed via the Store’s library interface.
