How to turn on Cortana in my desktop PC

When I click in the search box in the bottom task bar, and then click the top left to get the menu, the option for Cortana only shows the switch button in Off position, and it's greyed out so there does not appear to be an option to enable it.

I believe you need to change your region settings. What is your region set to? Change it to US and then try.
