Perhaps one of the biggest features in Windows 10 is the arrival of Cortana, Microsoft's answer to Apple's Siri and Google Now. Cortana is the "world's first" digital assistant capable of helping users on many tasks. The more it learns about you, the more it understands you and it'll be able to assist you more efficiently.

On Windows 10, you can simply say "Hey, Cortana" to have the service immediately answer questions about weather forecasts, set reminders, search the web, find virtually anything on your PC, keep track of flights, calendar, packages, and a lot more – Heck! Cortana can even tell you joke if you need a distraction after a long day of work.

As good as Cortana is there is the issue of privacy as Cortana as inevitably it has to collect various pieces of information and personal data to learn to assist you accordingly.

Some information collected by the Microsoft's digital assistant includes information about your contacts, calendar, location, internet history and favorites, speech, inking and typing, and more.

Although, I personally believe that Cortana is a great tool that will only get better with time, we have to understand that many users will find Microsoft collecting certain pieces information as an invasion of privacy. As such in this how-to guide, you'll learn the options Microsoft is offering to turn off Cortana and stop personal data gathering.

Follow these steps to turn off Cortana in Windows 10

It is actually pretty straightforward to disable Cortana, in fact, there are two ways to do this task. The first option is by launching Cortana from the search bar on the taskbar. Then, from the left pane click the settings button, and under "Cortana" (the first option) and slide the pill switch to the Off position.

The second option is by launching the Settings app and on Privacy, go to Speech, inking, & typing, and click Stop getting to know me.

Either action will turn off Cortana deleting everything the assistant knows about you on this devices. Previously collected data from Cortana's Notebook will not be deleted.

Deleting personalization data from the Microsoft servers

To delete any remaining type of Cortana's data and personal information, such as Notebook, Reminders, Places, from your account, go to the Bing Settings' page. Using the account you are using on your computer, click the Clear button for both "Clear personal info" and "Other Cortana Data and Personalized Speech, Inking, and Typing". In both cases, confirm the deletion and you'll be good to go.

Turning off additional data gathering options in Windows 10

If you want to stop Microsoft from collecting personal information, you can go to the Privacy settings page and disable Send Microsoft info about how I write to help improving typing and writing in the future.

In the same way, you can turn off data collection for location by going to the Privacy settings page and disabling Location globally. Please note that you can also disable location per app. You can even turn off location for Cortana, but at the time of this writing, this option cannot be configured just yet. Disabling location globally will also disable the feature for Cortana.

Things you need to know

While Microsoft is providing different ways to turn off Cortana in Windows 10, there are a few things you may want to know about this feature and data collection:

  • You can only disable Cortana per device. You cannot simply disable the digital assistant in one device and expect to be turned off on every Windows device you own
  • The name you set Cortana to call you is also set per device, not globally
  • You can clear data and personal information that Microsoft collects using Cortana, but there isn't a button to stop collecting information globally in your Microsoft account
  • If you do not want Microsoft to store personal information in the cloud, turn off Cortana on all your devices, then clear all your personal information from your Microsoft account
  • If you disable Cortana in one device, then you clear your information stored online, but if you have another device using Cortana, then that information will once again be uploaded and stored in your account
  • Turning off Cortana will make Windows 10 less efficient in trying to make better suggestions for you
  • Yes, the search bar on the taskbar will continue to work. It won't disappear because you disable Cortana. However, you will be limited to simple searches (locally and from the web)
  • You can always turn on Cortana by opening search on the taskbar, going to the Settings section of the left panel, and sliding the pill switch to the On position. You can also do it via the Settings app > Privacy > Speech, inking, & typing and clicking the Get to know me button

Wrapping things up

As you can see, Cortana's settings and how Microsoft collects information is very fragmented. Currently, you have to go to different locations to turn off Cortana and other features that will trigger data collection. Users have to access a web page to clear stored information in their Microsoft accounts, and the Bing Personalization page only offers options to clear users personal information. It does not provide an option to stop personal data gathering completely. In part, this is because, disabling data collection will also affect Bing search results -- after all the digital assistant is powered by the Microsoft's search engine.

Furthermore, the only way you can access Cortana's Notebook, Reminders, and Places is from the device itself, Microsoft does not provide access to such information on the web. So, if you have multiple Windows 10 devices and you did disable the assistant and other data gathering after clearing the data chances are some of your personal information will upload back-up to your account.

Of course, this is just the beginning, and the work is far from done. Like Google, Microsoft also offers a dashboard, which is the home for users to control their accounts, devices, services, and subscriptions. I think it would be better if everything the software maker offers were located in a single location to simplify the user experience.

Microsoft is working to include Cortana on most Windows 10 devices for the July 29th release, including PCs, tablets, laptops, and phones. However, at launch the digital assistant will be limited to certain regions, including United States, United Kingdom, China, France, Italy, Germany, and Spain.

And there are other big plans as well. Microsoft has already announced that the digital assistant won't be exclusive to Windows 10, and it will be releasing a standalone app for Android phones, iPhones, and iPads in the near future. However, the app will have limited functionality, because of the nature of the app unable to access part of the different operating systems.
