This is a lame question, but...?

ok, I know this is a stupid question, but umm on the airplanes (the big ones) at the airport, umm does the farthest seat that you can get even have a window? like i am moving & flying, & i like to have a window seat, & i chose the last row, window seat, I wasn't sure what seat to get, but I just wanted to know if it is even a widow(ish) seat if that made any sense. it said my seat isn't final, but just in case. Like I said, it's a lame question, but I could find anything on it, gar. If there is ANY thing i would be greatful.
