I have read many articles on this and for the most part nobody understands what is being ask.When you start internet explorer and hit the down arrow,some previous web sites show up.This is how to solve the issue.
1.Start Internet explorer
2.click tools
3.click internet options
4.click content
5.click autocomplete settings
6.click auto complete history
7.At this point I took the check mark out of address bar.close internet explorer and restart it.Now click the arrow down and you should not see anything.Hope this helps.
