A little oddness

So my computer updated, and it FINALLY lets the lockscreen dismiss when I first start it up, something that the Creators Fall Update had broken.  It is doing something if I keep it going for a while, either closed or open, where it's acting like the touchscreen is being touched when, in fact, it is not.  Restarting solves it, but it's weird.  I've had to do it twice in the last 24 hours.
