When I upgraded to Win 10, I had no issues whatsoever. Cortana worked as it was supposed to. Now, it doesn't work at all. I have changed nothing on my end. No updates, last update was yesterday and even after that update it still worked. Right clicking on the task bar to show the search bar does nothing, can't even type in the search bar. Searching for Cortana in the settings menu does nothing as when I click on "Cortana and Search Settings" it just goes directly back to the main settings screen without bringing anything up. Some help would be great. Window 10 pro 64bit.
