No, you don't need to download a different windows, you just need a program like photoshop or gimp to be able to make them. Paint does not work for preset making.
You also do not need to download the equip, it can already be found in the game. You just need to color the wing models from the folder (in the my_presets folder) for them to work.
And you also need to make sure when you put the preset in, make the name in the material file (the notepad) matches the names of everything.
