Nothing changed bar this week's M$ updates, but the black panel (which shows available networks and 'Connect automatically' and 'Connect') does not appear when I click on the wireless taskbar icon. All else normal and I have to now connect using PC Settings 'show available networks' and taskbar icon does show connected network on mouseover.

Also I see taskbar calendar does not open nor does action centre although 'Notifications' number displays.

NB Cortana was 'killed' by me during recent re-install of W10

Weird!!
