Have you been playing with language settings? I changed to UK English for fun, restarted, and Cortana was missing. Changing back to US brought her back.

Re: how do I reinstall cortana?

You can't uninstall Cortana. Have you checked your language and region settings?

To all those claiming it can't be uninstalled, note that the poster said they were using a dev phone. Using dev utilities, most things can be uninstalled.

There is no Cortana download in the store I believe (even hidden), as it is never updated through the store but through Windows Update instead, so the only way to reinstall is a hard reset.
