Oh the side(probably on the right), theres your "Solution Explorer". It should say your project name, then show something that says "Project" below it, then below that should be your form names, which you can double click on to navigate between them, Double click the "Project" one and on the Middle Right there should be a dropdown that says Icon: above it. Click the DropDown and press Browse, then find your Icon you want. Just for future reference.
