We did virtually the same thing to our house years ago Chunkster.
I would recommend the 3/4-inch plywood however, as if the window is a large expanse, the thinner plywoods may "flex" in the middle. Also, make sure the plywood is attached to the house very secure and tight as to eliminate the possibility that during a hurricane or other high wind scenario, the wind could not get underneath or behind the plywood and more or less pull it off the home. If the window(s) are really wide, you may consider a center attachment piece - or "batten strip" to additionally secure the plywood to the home.
One other added thing we did was cover the window side of the plywood with some old rather thick quilt type bedspreads we got at the various reuse centers. Used carpet glue to attach them. Probably not needed but did it as feel-good extra protection.
Good luck!
