Personalised ads, also called targeted ads, on Microsoft websites are chosen based upon who you are, making them more relevant to what interests you. We’re able to make these personalised ads possible by using technology called “cookies,” which are small text files used by websites to help remember your interests and preferences. As a consumer, if you’d rather not see these kinds of ads from Microsoft, you can change your preferences. Keep in mind that ads will still appear, just not ones that are based on your interests and preferences.
