On April 3, 2015, Microsoft announced that the Do Not Track option will no longer be a default setting in its Windows browsers.
Do Not Track is a technology that enables users to opt out of tracking by websites they do not visit, including analytics services, advertising networks, and social platforms.
According to Microsoft blog, the change was required to reflect current privacy standards for tracking preferences. However, the company “will provide customers with clear information on how to turn this feature on in the browser settings should they wish to do so. This change will apply when customers set up a new PC for the first time, as well as when they upgrade from a previous version of Windows or Internet Explorer”.
