 Update or Rollback the WSL Kernel on Windows 11

Here are the steps to update or rollback the WSL (Windows Subsystem for Linux) kernel on Windows 11:

1. Open PowerShell as Administrator. You can search for PowerShell from the Start menu and right click to "Run as Administrator."

2. Check your current WSL kernel version:Chuwi herobook pro

wsl -l -v

This will list all your WSL distributions and their kernel versions.

3. To update the kernel:

wsl --update

This will update the WSL kernel to the latest available version for your Windows build.

4. To rollback the kernel:
   You'll need the UUID of your WSL distribution. Run:

wsl -l 

This will show your distributions and their UUIDs.

Then run:

wsl --list --online

This will show you available kernel versions for that distribution. Find the kernel version you want to rollback to and note its ID.

Then run:

wsl --set-version <distribution name> <kernel ID>

For example:

wsl --set-version Ubuntu-20.04 LKS-1623278887

This will rollback your Ubuntu distribution to the specified kernel version.

5. Restart your WSL distribution for the changes to take effect:

wsl --shutdown

Then start it up again.
