How to install kali Linux and upgrade it to the full version running kex server on windows 11

First thing is to ensure that vm / hypervisor / subsystem for Linux windows are installed on your system! After rebooting your system you then upgrade wsl to wsl2 via command prompt in windows.

Open PowerShell as Administrator.

To install WSL, run this command:

dism.exe /online /enable-feature /featurename:Microsoft-Windows-Subsystem-Linux /all /norestart

Enable the Virtual Machine Platform optional feature by running the following command: 

dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart

Restart Windows 

Download the latest Linux kernel update package and install it: WSL2 Linux kernel update package for x64 machines

https://wslstorestorage.blob.core.windows.net/wslblob/wsl_update_x64.msi

Set WSL 2 as your default version. Open  PowerShell as Administrator and run: 

wsl --set-default-version 2

You can now install WSL 2 distros from the Microsoft Store
