Why would a passenger airliner be missing windows in the fuselage?
Most of them are where there is a divider between sections or there is a lavatory there.

Here are the layouts for the Garuda A330-200 and -300. As you can see the divider between the classes (Between Blue row 11 and green row 21) and the lavatories (Between rows 31 and 32) are located where the missing windows are in the video.
