The Windsor is an attempt to simulate, with a common tie, the look of a knot the late Duke of Windsor was known to wear, which was, in fact, a four-in-hand tied on a much wider (and, I suspect—though I have seen no documentation on this point—differently shaped) piece of material than common ties.

I’m not sure what relevance that has; I learned it about the same age, also from my father (who I suspect didn’t learn it from his father, whose personality, age, and socioeconomic background probably would not have inclined him to jump on that particular newfangled fashion trend.)
