I have a win 8.1 machine and a win 7 machine on the same homegroup. When I'm on the win 8.1 machine and look in windows explorer, my user account for win 8.1 shows the user account image I've selected for it, but the win 7 machine just has a generic icon (the silhouette of a person image). My question is, why isn't the user account image on my win 7 machine visible on the win 8.1 machine? All other connectivity with the homegroup works fine.
