Power windows as such should not stop engine from starting, apparently.....but I have not traced down everything yet in power distribution, a little bit confusing.... Anyway, one thing has to be learned: one should NOT operate (open/close) more than one window at a time. BLown fuse have been reported frequently due to this "abuse".
EDIT: specific power window fuse as such does not stop engine...but if it is the main fuse that blows, then all will go dead.
