This morning my PC had several icons in the taskbar (where the clock is) and the Show/Hide arrow was visible. This evening, 18 Microsoft updates were downloaded and installed. When I rebooted, no icons or arrow were displayed. I rebooted again but no luck. I started my browser (Avant) and minimized it, which usually goes to the taskbar but it wasn't displayed. I started the browser again and the browser that was already running was displayed, which is good. Has anyone else had this issue and know how to correct it?
