People may track your online behavior as you browse the web. This allows marketers to create a profile based on your interest and provide you with relevant advertising messages. It's obviously not a good thing to allow people to observe what you do online. You need to disable advertising ID by following these steps:
Click on the Start menu, click on 'Settings' then click 'Privacy'. Turn off the first option to disable interest based advertising. For a higher level blocking of ads, open any web browser and go to the Microsoft Privacy Ad Settings page and sign in to your Microsoft account. You can disable interest based ads at browser, Windows and Microsoft account levels.
After disabling interest based ads, marketers won't be able to track your online behavior and you will still get ads, but they will be generic ones.
