I don't have cortana, how can I activate it?

Question

I only have "search in windows" option and I don't see any configuration to activate cortana:

I've seen that a lot of people have problems with their region, but that doesn't seem to be my problem, I don't even get that message. How can I activate cortana? I used to have it. I don't know if it dissapeared with some kind of update or maybe I stopped some kind of service... How can I activate it?

Edit: I know it's only available in some regions and countries, but I also know it is available in Spain. The only part important there is that on the left pic it says "Search in Windows" instead of something related with cortana and on the right pic I have no options to modify anything cortana's related.^

I'm using Windows 10 Education 1607

Answer 1

Cortana is not available in the EDU version of Win 10 https://www.reddit.com/r/Windows10/comments/4vnt7y/cortana_officially_removed_from_windows_10/

Answer 2

Install windows updates. Early Windows 10 shows the search box but after a couple updates that changes to cortana. Do this by going into the [Settings] and then selecting [Update & Security] Then click [Check for updates]

Answer 3

On build 1607 the most common solution is by using the command

Get-AppXPackage -Name Microsoft.Windows.Cortana | Foreach {Add-AppxPackage -DisableDevelopmentMode -Register "$($_.InstallLocation)\AppXManifest.xml"} . 

this powershell command worked for me.
