Granted there's nothing particularily lurid there, they're just not things I'd want visible to anyone who uses my computer (especially were it to be stolen).
I know in IE 7 you'd just go into the registy, and under:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\TypedURLs
You'd just delete everything except the default. When I go into that key now, there's nothing there but the default value.
Any ideas?
