[Harry Potter] What would have happened if they didn't know Harry was a horcrux and took out Voldemort anyway?

Basically, what if they never knew Harry was a horcrux and he didn't go willingly to his death but they still somehow took out all his other horcruxes and then him, perhaps by reflecting his own killing curse back at him somehow again?

Voldemort's shade continues to cling to this world, seeking a host for possession or else being available for the resurrection ritual.

You could get a soft win against him by killing every last Death Eater and trying to make sure nobody is tempted by his shade, but Voldemort is a one-man army and is going to keep trying to take over Britain until he gets lucky.

Also, Harry *might* be secretly immortal until you remove the horcrux.
