Steps to reproduce


Repro Steps:

  1. Add more than one language/keyboard layout on Windows 8 or newer and visit a website. Regardless of the InPrivate mode, the Accept-Language header can be used to track users.
  2. Open IE and open F12 network tool and click start capture
  3. Load a webpage
  4. Look at the Request header details on the GET request you will see “Accept-Language”

Repeat the steps above with IE running InPrivate

Expected Results:

The InPrivate mode to not reveal language list to the websites. Currently the Windows settings is all-or-nothing but clearly suggests the list is a concern of privacy. It is not very difficult to end up with a language list (i.e. Accept-Language header) that helps to identify, or even uniquely identifies the visitor.

Actual Results:
