I have upgraded to Windows 10 first my laptop and, more recently, my desktop. I use Reliability Monitor daily.

Three days into Windows 10, Reliability Monitor on my desktop reported an application failure on Friday: "Cortana stopped working".

There were ten further such reports yesterday. My laptop has not reported this event so far. Everything in Windows+S>Settings is set to off on both machines - I do not want Cortana. Settings>Privacy is set to much the same on both machines, except in Speech, inking and typing.

I see that my desktop is set to "Get to know me" and my laptop is set to "Stop getting to know me".

Administrative Tools Event Viewer lists "Faulting application path: C:\Windows\SystemApps\Microsoft.Windows.Cortana_cw 5n1h2txyewy\SearchUI.exe".

I ran "sfc /scannow". No integrity violations were found. I wonder if any other users have further suggestions to overcome my issue.
