While I do not for sure, it seem likely that through the years the king/queen have been here a few times since it is within walking distance to the Windsor castle gate. As a result, this relatively simple church has some rather fancy adornments.

St. John the Baptist Church, Windsor

Our first house sit in England took up to Slough, a gritty working class town just north of Windsor. Needless to say, we visited Windsor multiple times. On our first trip, we started with a look around St. John the Baptist Church, just down the street from the Henry VIII gate entrance to the castle.
