SOLVED: What is Cortana in Windows 10

Microsoft describes Cortana as a digital personal assistant while that is a fair description, it hardly tells you what Cortana does.  Cortana is a search tool that can be activated by typing text in the ASK ME ANYTHING field to the right of the START button, or it can be configured to use voice command.

In addition to searching the web and returning relevant information, like Apple’s Siri (bad) or Googles Voice (very good), Cortana has an ever increasing number commands that relate to your performing tasks.  This list includes starting applications, making changes in your calendar, track flights and sooo much more.  Personally I have turned VOICE COMMAND on, and now I say things like HEY CORTANA, START WORD, when I want to Microsoft Word to launch.what-is-windows-10-pda-microsoft-cortana

For Cortana to function, the current Windows user must be signed in with a Microsoft Account (as opposed to a local account) and must have their Windows 10 REGION set to one of the support countries.  In November 2015 those counties include the US, France, Germany, Spain and Italy.  By the end of the month India will be included in that list.  Microsoft wants Cortana to impress, and that requires localized knowledge including localized language.  This means Russian Cortana, for example, should be ready in 2016.

THIS is Microsoft’s Cortana FAQ’s which is surprisingly to the point and useful:

When I use Cortana, what information is collected and where is it saved?

When you use Cortana, Microsoft collects and uses information including your device location information and location history, contacts (People), voice input, searching history, calendar details, content and communication history from messages and apps, and other information on your device.

This information is saved on your device, in your Cortana Notebook, and in the cloud on the dashboard.

Turning off Cortana clears the interests and information on your device, but won’t clear the information that’s saved on the Notebook or in the dashboard.

How do I manage the information Cortana knows about me?

You can add or remove individual items, such as interests or places that Cortana has saved about you, in the Notebook and on the dashboard. The Cortana Notebook will sync with the information in the dashboard, and you can manage them in either place. and Microsoft apps may adjust their behavior based on the changes you make to your interests or favorites in the Cortana Notebook and the dashboard.

Cortana is a truly personal assistant, providing personally relevant suggestions and alerts. In order to do that well, Cortana needs to understand certain information about you, such as interests, location, and preferences.

Can I control what data Cortana collects?

Go to Cortana > Notebook > Settings > Other privacy settings > Speech, inking, & Typing, and then, under Getting to know you, select Stop getting to know me.

I use Cortana on multiple devices. If I turn off Cortana on one device will that turn Cortana off on my other devices?

Turning Cortana off on one device doesn’t turn it off on other devices. You have to turn Cortana on or off for each device you use.

Why can’t I turn off location for Cortana in location settings?

As your personal assistant, Cortana learns about the places that are important for you and when you visit those places. This allows Cortana to give you personalized help, such as traffic alerts before you leave for your next appointment or location reminders if you’ve asked her to alert you when you’re near a certain location.

Cortana can’t work without device location information.

How often does Cortana collect my device location information?

Cortana collects your location periodically even if you’re not interacting with Cortana, for example, when you connect to Wi‑Fi or disconnect from Bluetooth.

How does Cortana know when I leave for work or home when that information isn’t in my Calendar?

Cortana learns your routines by collecting your location changes throughout the day so she can give you relevant recommendations at the right time. For example, Cortana can try to determine where you live and work, and if you verify those locations, she may give you a traffic report at the time you usually leave for home or work. These location identifiers are saved in your favorite places.

What information does Cortana collect from my contact list (People)?

In order to personalize your experience and provide the best possible suggestions, Cortana collects information about your contacts (People) including their title and/or suffix, first name, last name, middle name, nicknames, and company name. If you communicate with someone via email, or SMS, Cortana collects that person’s email address or phone number.

Does Microsoft or Bing plan to use any of the data that Cortana gathers to sell advertising or otherwise mine information?

No, Cortana doesn’t use the information in the Cortana Notebook to send targeted ads. Ads may accompany search results that Cortana delivers—just as they do when you do a search on

Does Cortana share data with other Microsoft apps or services?

Cortana allows you to connect to third party applications, such as Facebook, for additional personalized experiences using information you’ve shared with the third party.

Can children use Cortana?

When I use Search, does it always include web results and send information to Bing? Or can I turn the Search online and include web results setting off?

The Search online and include web results setting is turned on by default. To help you find the content you want more quickly, Search automatically suggests search terms as you type. These suggestions are provided by Bing, and can come from apps, settings, or files on your device, as well as from OneDrive and the Internet. When the Search online and include web results setting is on, Windows sends what you type or say to the Bing service, which interprets it in real-time to provide auto-suggestions.

To turn the Search online and include web results setting off, go to Search > Settings, and then, under Search, turn the Search online and include web results setting off.

To clear previously typed Bing search terms, go to > Settings > History, and then select Clear All.


How do I provide feedback and suggestions for improving Search? And does Microsoft really pay attention to my feedback?

You can send feedback directly from Search. Go to Search, and then select the Feedback icon. Type your feedback and include a screenshot—or if you’re using Speech, use your voice to dictate your feedback, instead.

We do listen to your feedback and are always working on improving our products and services. The ability to change between Celsius and Fahrenheit when you’re looking at the weather in Cortana came from customer feedback. So did the ability to download the homepage image.

How does Search use my device location information?

If Cortana is turned on, the Search app has access to your device location information and will automatically send it to Bing when Cortana suggests web search terms and results. Bing also uses your device’s location as described in the Bing privacy statement.

If you want to turn off the device location service for the Search app, turn off Cortana and then turn off location for the Search app.

To turn off device location services for the Search app, go to Start Start icon, then select Settings > Privacy > Location, and then, in the Choose apps that can use your location list, turn the Search app setting off.
