With Windows 10, the IE will get a new makeover and a new name Spartan browser. As we have fetched information that the new browser will be highly interactive and personalized. So turning on DNT will certainly put a bar on its browsing experience.
According to W3C:
Key to that notion of expression is that the signal sent MUST reflect the user’s preference, not the choice of some vendor, institution, site, or network-imposed mechanism outside the user’s control; this applies equally to both the general preference and exceptions. The basic principle is that a tracking preference expression is only transmitted when it reflects a deliberate choice by the user. In the absence of user choice, there is no tracking preference expressed. (Emphasis added.)
If you are thinking that is it the end of private browsing? Certainly not. Microsoft will include the setting to enable DNT, and will provide necessary instructions on how to enable it. Microsoft said,” Put simply, we are updating our approach to DNT to eliminate any misunderstanding about whether our chosen implementation will comply with the W3C standard. Without this change, websites that receive a DNT signal from the new browsers could argue that it doesn’t reflect the users’ preference, and therefore, choose not to honor it.”
