I had Cortana then it gone. How do I get it back?

[Windows Central Question]

I used it once, the next time I went on line it was gone.

She may have left you for someone else. Alas, I hate it when girls are fickle like that. Microsoft should have programmed her to be more loyal. (Sigh.)

Seriously, to be able to assist you, please register for an account, then return to this thread and provide us with a bit more information. We need to know what kind of device you're trying to use Cortana on. Windows 10 PC? Windows 10 Tablet? Windows Phone 8.1? Windows Phone running Windows 10 for Mobile? What are your region and language settings? Is location services turned on or off? (Cortana is disabled if you turn off location services.)
