Dear @mikeyland1981 ,
The feature of Window scaling is not MWG specific. The same work for all IP communication to decide on biggest possible TCP window. In older Versions the TCP window scale might get set to "2" by default. The reason was, to address best possible usability as there are still devices not supporting window scaling. As the internet grow and bandwidth increase it make sense to review this setting. Bigger TCP window lead in some circumstances also to lower speed due to my personal experience. Below you can find Microsoft reference with all details about TCP window scale:
