Recently my computer guru had to bail me out of a mess I created while downloading the most recent updates to windows 10. Now I find that when I go on GTT, & I have Notifications, I read them, respond, etc. but they do not clear. Before my windows update, whenever I looked at my Notifications, they would clear off. What do I need to reset or fix so that once I've looked at my Notifications they will auto clear as before. I'm not a very dialed in computer person. I've always worked best with nuts & bolts & not keyboards. Thanks for the help.
