Last night, I hit "update and shut down" when I logged off. This morning I first noticed the the Edge icon was gone from my taskbar. I then found that left-clicking on the windows icon now doesn't bring up the Windows 10 start menu. I can still right click and pull up an old start menu. Several of the othe icons are not working as before- notifications don't pop up, the clock popup window is gone, the search icon next to the windows icon doesn't function, My HP Help icon, sticky note icon, Google Chrome icon, and File Explorer icon on the task bar do still work. I can navigate the internet using Chrome but it appears that pretty much all the new Windows 10 functions are disabled. I welcome any suggestions for a fix.
