Cortana on Windows 10 will only work in specific regional settings and languages:
Regions: China, France, Germany, Italy, Spain, United Kingdom, and United States
Languages: Chinese (Simplified), English (U.K.), English (U.S.), French, Italian, German, and Spanish
It is currently unclear at which regions and with which languages Cortana works, but we use it under United States with English (U.S) settings. That has always worked and will continue to.
How can I tell if Cortana works with my current region settings?
Right next to the Start menu icon you should have either a magnifying glass or a line that says ‘Search the web and Windows’. Whatever it is, click on it and then in the menu that opens up click on the gear icon.
If you see ‘Cortana isn’t supported in your region…” then that means… that you’ll need to change some settings to make it work. It’s easy.
Just please be aware that changing your region settings might render the Microsoft Store unavailable, as well as make some things that you purchased – music, games, memberships etc. – inaccessible. At least until you change back to the old settings.
Steps to change region settings and make Cortana work
3. Pick ‘Region & language’.
4. Change the country or region and the display language to the same option (for example UK and English (U.K)), one of the supported and currently active options. If you’re not sure if the language/region you’re looking for is active, just try it. We used the US settings, as we’re sure that that works:
United States + English (United States)
5. Make sure that under English (United States) you see the words “Windows display language”. If you don’t, click on English (United States) and click on “Set as default“. If you chose a different language, you should set that language the “Windows display language”.
10. Restart your computer for the new region and language settings to take effect.
And that’s it, that should make Cortana work. Windows might start downloading Cortana and other features that were not available in your previous region. In which case you’d have to wait until the download is finished and restart your computer. Windows should automatically notify you about these steps.
Once you made the changes click on the magnifying glass line next to the Start menu icon or the line that says ‘Search the web and Windows’ next to the Start menu icon. If Cortana is set to ‘on’ (click on the gear icon in that menu you just opened to be sure) then she will start socializing with you immediately. That may look like this:
