-- The above process has been updated to be compatible with VirtualBox 7+, in which VBoxSDL was removed and vboxmanage should be used in its place. A small wrapper powershell script is used to achieve this.
 - It was noted that Windows builds above `20H2` seem to have issues installing WSL2. We may have to wait for a patch from Microsoft to fix this. Our devs are currently using build `20H2`.
