Just applied the directions will reboot and give it a few days testing before further comments. random crashing has been ongoing, hopefully this fix is the answer. Also of note in my case, “enable archive hints” was enabled so I disabled it. “enable archive property sheets” was already unchecked. So at present only “use explorer shell extensions” and enable explorer preview" are left enabled.
