Delete and Remove all Personal Data from Cortana on Windows 10

Cortana is the defacto personal assistant Windows 10 comes with, and its used for many things apart from using it for search. That said, Microsoft also collects data from Cortana to improve the user experience. It includes voice, interests, and the data on the device. In this guide, we are going to tell you how you can delete and remove all personal data from Cortana on Windows 10.

Cortana can do a lot of things for you including basic PC operations, work on the lock screen, run custom tasks, and so many other things. It can also sync back settings across PCs.  If you have never used Cortana, you can enable it right away, and sign-in with your Microsoft account for the same experience across the devices.

Now if you have already used it a bit, and wonder if signing out will just fix it, it won’t. You will need t do more! This post will show you how to clear Search History and remove and delete all Personal Data from Cortana on Windows 10.

Delete all personal data from Cortana

Windows 10 offers a plethora of options for privacy which you can configure to keep your privacy safe.  As you are signed in with your Microsoft Account, it can collect data like your search queries, calendar events, contacts, and location

The first thing you need to do is Sign-out of Cortana. That way no further data collection will take place. Cortana collects data on your PC, keeps a copy there, and also syncs back to the cloud. So we will need to delete data from two places.

  • Re-confirm to finally turn it off.
