I posted the same question earlier about Bodak's. They are even more dangerous since they have a death gaze whose victims rise as Bodaks in 24 hours.
My solution for my campaign world for the bodak was simple. If the dead body is exposed to any sunlight in the 24 hours before rising as a Bodak then the process is cancelled. This kept the Bodak's from destroying entire towns adn turning everyone into undead.
I am sure with a little thought you could do the same for Shadows. If there is a time period before the creature becomes a shadow then make it not work if the body is hit my any sunlight at all.
