Microsoft admits that when it switched on "do not track" by default in Internet Explorer 10 back in 2012, it was "welcomed by many." However, the company now has to switch it off to comply with the latest industry standard. The newest World Wide Web Consortium (W3C) draft for the feature says it "MUST reflect the user's preference," meaning you have to turn it on to activate it, just like on Firefox or Chrome. Redmond explains that it has no choice but to change the default, else advertisers can argue that it doesn't have to honor any DNT signal from Microsoft's browser. http://www.engadget.com/2015/04/04/m...-do-not-track/
