Settings, Game icon, Start Unity scene...

Hi everyone! I would like to know how may I change the icon ( When a I build it on an .exe), how may I remove that start Scene that says: "powered by Unity" and how may I put that start settings, like: " windowns resolution" and "Quality" to be automaticaly and hava a default value.

Change the icon and default resolution in the player settings. Change the default quality in the quality settings. Remove the splash screen by buying Unity Pro.
