There are several way to do it. But i would need more on how detailed your models is.
Can you put a picture up of your model? Or name the type?
I'm assuming you want to make real windows? How detailed do they need to be? Just squares, chamfered edges, or rounded?
Keep in mind that if you make all windows in real geometry the polycount will be greatly increased. And the rendertime. Also more detail will take longer.
I usualy use a tubeshape (or square) as a window and make a ProBoolean on imprint mode to cut the windows into the surface. Then you can extrude and chamfer the edges if you need to.
