You get a code signing cert from any CA that sells them and sign your executables yourself. Certs can be as cheap as $50 a year / $250 of extended validation ones. Stay away from Comodo though, they are staffed by predominantly incompetent idiots and their validation process is a circus and nightmare in equal parts.

If you get an EV cert, it gives you an instant pass through Microsoft's SmartScreen, meaning that the warning the Edge (or what it's called bow) shows upon downloading is less scary.
