My questions concern the gaps in the otherwise continuous cabin window pattern observable on all Boeing 767s, especially just ahead of the wing.
Next week I will be travelling by Air New Zealand 767-300ER on a trans-Pacific flight. My seat assignation is in row 13. The first question is: in that row, am I doomed to a "non-viewing" window seat? (BTW, don't you just love that oxymoron?)
Although I've flown in plenty of 767s before, this will be my first time on an NZ example. As we all know, every operator has a different seating layout, particularly in this area of the cabin---so my previous experience with other airlines' 767s means little. To find out the NZ 763 cabin configuration, I've checked all the sources I can find; the most helpful has been SeatGuru, which seems to indicate that everything will be just fine and I won't be staring at a blank wall after all. But is it true?
My second, more general question is: why are those windows omitted anyway? I have always believed it was because there were extra frames at those stations in the fuselage structure. Is this correct?

The reason there are no windows at those positions is due to "riser ducts" these are ducts that feed the air from the Air Con packs under the center wing to the ceiling where it's distributed throughout the A/C.
It differs on A/C types the 767 for example the air leaves the packs going fwd of the center wing tank and up into the rear of the fwd cargo where it enters a mixer unit, from there it's fed to the risers. As you can see the 777 has blank spaces as well.
There is no window frame at these points it's just the skin as the frame if installed would take up to much space.
The 747 has 3 risers each side the air leaves the packs rearward and goes up in the fwd part of the wheel well it then goes into the mixeror air plenum on top of the center tank, from there it's fed to the risers. As you can see the A330 has one fwd of the wing it's possible it may have one aft of the wing as well.

Well yes you are doomed. Simply by the mere fact that you are in row 13. I don't know of anyone who has sat in row 13 and actually made it to their destination. I'm not saying it's not possible. I'm just saying I don't personally know of anybody.
