...on Boeing test aircraft??
I have seen what looks like a red plate? covering over a passenger window near the front of the aircraft on the 777, 787 and now the 748.
I would really like to know the reason behind this??

I'm not sure I know what you are talking about (someone else might be more knowledgeable), however I think it is for flight test instrumentation. They will replace a window with a plate with auxilary sensors attached such as additional pitot tubes or other equipment needed to check out systems.
