Go through the normal route of installing WSL2 then follow below for terminator instructions;
- install VcXsrv for X11 (tried with cygwin but terminator rendered badly on secondary desktops) on windows
- install xfce4 and xfce4-goodies on ubuntu
- install terminator and test it opens. If you have installed the zshrc file from here it should work. Otherwise you might need to fool with your DISPLAY variable
- following instructions from here create a vbs file in order to launch terminator from a shortcut (copy of script used is in dotfiles repo)
