The missing icons is a clue something is up beyond the update. Since this is too new I can't write what's up but head to how I test. With my spare admin local account.
Since this update, my Fitbit HR has had trouble syncing. It only works after I shut down and restart. Periodically, I lose the icons on the taskbar, which makes it impossible to move from app to app. I can get to another app by minimizing the screen, but I can't get back.
1 Feature Update and 2 Security Updates were added that day. I'd like to uninstall the Feature Update, but the list of Updates that Windows will allow you to delete doesn't include this Update. So, I seem to be stuck with an Update that doesn't do anything I want and doesn't let me do what I want.
