There is a driver update v416.94 for my GTX1080ti which I installed before I decided to restart the system, to instal the cumulative update KB4467702. I never install the Experience program when I update the graphics card driver [I always choose the custom install option and uncheck the Experience program installation], which is what may cause problems with the cumulative update KB4467702 as per my OP. Anyways, everything so far is running OK after the geforce driver update and the cumulative update KB4467702.
