New Computer 6 mos old, Win 10 Pro ver 1709.
When originally set up, Cortana was there in Settings, via Taskbar, on Search window etc.
During original set up, I turned everything OFF that I could and never looked at it again.
At some point Cortana went missing from what appears to be everything though Cortana shows in Task Manager>Processes tab>Background processes.
No Cortana Settings entry, no Cortana icon on the taskbar search box.
Pls help.
