To update the WSL (Windows Subsystem for Linux) kernel, you need to install the latest Linux kernel update package. Here are the steps you should follow:

  1. Download the latest package:
  2. Run the update package: After downloading, double-click the MSI file to run it. You will be prompted for elevated permissions; select ‘yes’ to approve the installation.
  3. Set WSL 2 as your default version (if you want new installations to use WSL 2): Open PowerShell and run the command: 
       wsl --set-default-version 2

After completing these steps, your WSL kernel should be updated to the latest version available.
