Reply To: After the bevel command on the window features, does the upper corner, technically, contain a quad that is no longer square?

You’re right on @sjp , it does become non-square and in this case just doesn’t matter. You could snap the other two vertices vertically and horizontally if you’d need it to be square again. If you need it to remain square the whole time, you could try doing an inset instead of a bevel. Hope that clears things up!
