Cortana is the voice command enabled personal digital assistant of Windows OS which first came with Windows Phone 8.1. Later on it came to Windows PC operating system with Windows 10. Now Cortana in Windows 10 has a plethora of features and customization options. Cortana is powered by Bing search, and whatever you search and browse using Cortana, Bing keeps track of the data so that it can serve you better next time. Bing records all that you have kept Favorites in Bing, MSN and Cortana. When you enable Cortana on your Windows 10 PC or tablet, the Bing uploads some information like calendar, contacts, location, browsing history, personalized speech, typing and inking across all your Windows devices. This helps in improving the suggestions, recommendations that you get from Cortana. Sometimes, Cortana also displays the search results by searching entries from your cloud account. Whatever text you search on Cortana, it remains in the activity history. The activity history keeps an account of the things you searched on Cortana. This enhances your searching experience, but if you expect privacy, then you have only one option, i.e, to disable Activity History. You have the full freedom to manage how your Cortana will know about your data and how it will show you.
