PARIS 2007: Rolls-Royce flies Boeing 787’s Trent 1000 engine on 747 testbed
Rolls-Royce has flown its Trent 1000 turbofan – the lead powerplant for Boeing’s 787 twinjet – for the first time, aboard the UK manufacturer’s 747 testbed. The first phase of the engine’s flight test programme is being conducted from Waco, Texas.
“We gave the engine a hard time for its first flight, but it did everything we asked. It was very stable and predictable,” says Rolls-Royce chief test pilot Phill O’Dell.

Quoting DeltaDC9 (Reply 17): The windows are usually not that particular config when it is a retrofitted 741.
Incorrect. Many airlines decided to dump the lounge (with limited seating) on the upper deck after the early-70's oil crisis, in favor of more seating. Thus, the section of the fuselage with the 3 upper deck windows were removed and replaced with a fuselage section containing 10 windows.
Example (same aircraft; first in 1972, last in 1977):

As I understand, all but the earliest 100s were built with windows in the frames, but plugs in the holes. Some operators intially opted for only three windows in the upper deck but later removed the plugs and installed windows. The fuse section was not changed.
