Where does IE11 store it's history for tiles when opening new tab?

I have build IE11 with all the plugins and it works great. I have done this many times, but i still have one thing i cannot isolate.

When opening a new tab, the history is shown of the native browser that is also installed. I want to isolate that so people do cannot see their history,

I have full isolated the Obvious places like %history% , %Internet Cache% ...

thanks!
