Clear stored username

[AndyA]

When logging on to certain websites, the pop up log in
field stores every single username ever entered. I use a
shared computer and would like for this information not
to be stored. Help?!

In Internet Explorer, Tools -> Internet Options -> Content ->
AutoComplete -> Clear buttons -> Uncheck all of the check boxes

I tried this but it did not work. I even restarted the
computer after trying it and they are still there. The
box where the usernames are has two keys in the upper
left hand corner. Beside the username is a box with a
mans head and then appears a dropdown menu with every
username ever used. Any other suggestions? Thanks!!
