Hello,
Thanks for bringing this to our attention. It looks like this case is not isolated to just one case, as all the post on this thread seems to be having the same issue after the update. Nevertheless, we would like to suggest a few basic troubleshooting step, so that we can eliminate all the other factors that could cause the issue, before we point our fingers to the update.
With that being said, I would like to suggest to check for driver updates, particularly with the keyboard and mouse, as a first troubleshooting step. Kindly refer to this link for more information and help regarding driver updates.
Let us know the outcome. We'll keep an eye out to your response.
