so if you are getting a dbus (failed to connect to the D-BUS- session bus: did not receive a reply) error while running a few gui applications on ubuntu bash for windows there is a fix fore this, your mileage may vary for some gui app just will not work!
Lets edit the file /etc/dbus-1/sessions.conf
sudo nano /etc/dbus-1/sessions.conf
and replace the line
this way it will redirect your dbus to your xming server on tcp port 0
