Sign in or Sign out of Cortana in Windows 10  

The Cortana process is used for Search (SearchUI.exe) application in Windows. It sits suspended in the background until needed though.

You can delete or rename C:\Windows\SystemApps\Microsoft.Windows.Cortana.
You have to close SearchUI.exe process and then you have like 2-3 seconds to do it.
It will prevent SearchUI.exe from running, but there might be some problems related to it.

Good morning(my time) Shawn. Messing around, learning the OS better, I just found out that turning off the Geofencing(Location finder) also turns Cortana off and sets her to normal search function like in Windows 8.1. You might want to post this warning in Location Setting tutorial(if you have one or are planning on it).

Good afternoon Cliff,

Odd. Cortana is listed as Search instead for me in the Location settings.

I'll write up a Location tutorial today. Thank you. :)

Seems to be only if Cortana is already on without doing original tutorial as far as i can see on mine. Not listed in location on mine.

Cortana was listed as Search in Location settings for me. Is it the same for you?

Where in search do you want me to check, as i followed your tutorial to shut part of Cortana off or bring it back to default for now ?

I was just referring to inside your Location settings like in the screenshots Cliff posted above. :)
