Instead of using default visual studio icon, one can create a custom icon and include it on all forms as well as executable file.
Every form has "Icon" section in the properties window and the AdvancedHMI project properties page will show it as well.
I have created some 16 colors 16x16 icons and have attached 4 for anyone to use (if you like them of course).
AHMI00 appears to be the most professional looking one and is my favorite.
