Clear Items from Search Pull-Down Menu

How do I clear the folder locations from my search box pull-down menu? It's one at the top of the search box. I have already cleared search history in iexplore and forms/password history in the internet options. In order to keep my computer secure, I want to clear the contents of the list that says "search-ms:" so that no one can see what folders I have accessed or made searches in.




Thanks
