Reti/Kings Indian; A Study

Here is a study of the Reti/Kings Indian. The game was drawn but White had so many possible combinations that I would like to ask for your opinion. What if any are the correct moves white might have made to create a win? I have placed my own possible moves that could be good for White and for Black. What do you think of this study? 1.
