but i want zsh

[josteink]

It's just Ubuntu. Apt-get zsh and then install oh-my-zsh (because I know you want that too).

Not sure if you're joking, but zsh will more than happily run on "Bash on Windows".

Chances are you can apt-get install zsh and then chsh just like you always do with an Ubuntu install.
