Windows 10 keeps track of most activities on your computer, including search and browsing activities. You will find below the steps to View and Clear Activity History in Windows.
Activity History in Windows 10
Your Activity History as collected by Windows 10 includes Apps that you use, files that you open and the websites that you browse on your computer.
When you are logged into your computer using Microsoft Account, Windows 10 sends your activity History to Microsoft in order to provide you with a personalized experience.
In case of multiple accounts, Activity history is collected for each Local Account on your computer and only the Activity history linked to your Primary Account is sent to Microsoft.
In order to help you manage your Privacy, Microsoft allows you to View, Clear and prevent your Activity History from being collected.
How to View and Clear Activity History in Windows 10
To View and Clear Activity history, go to Settings > Privacy > Activity History
On the Activity History screen, scroll down and click on Privacy Dashboard Link. This will take you to the Microsoft Privacy website which may prompt you to sign-in.
Once you are logged into your Microsoft Account, click on Privacy > Activity History.
On the Activity History Page, you will see your Activity History arranged by Data Types (Apps, Voice, Search, Browse, Media and Location).
