Go onto your desktop and right click on IE Explorer. On the menu that comes up click properties. On the screen that comes up there is a button that says clear history. Click that and that will clear your history on everything including the websites that you have visited recently. I have never tried this but, right beside of the clear history you see days to keep pages in history set that number to zero. I think that it will not store things any more.

Well you can clear it by going to:

Tools -> Internet Options -> Content -> AutoComplete -> Clear Forms

or just hitting the down cursor key til you get to what you want to delete, then hit the Delete key.

Alec - this would be a good thing to add into your registry prog. To find out wher it is, simply make a note of 1 of the entries in that drop down lost, then use Find in Regedit.
