If you still experience problems installing it.
I recommend you block it until the next cumulative update is released. Many are reporting the same problem too and it looks like this update is buggy.
Is there an option or work around to block updates or hardware drivers that might cause problems?
Yes, Microsoft has released a KB update (KB3073930) that will let users block or hide Windows or driver updates.
