IE6 Autocomplete problem

When I first set up IE on my PC, I must have enabled autocomplete because it remembers things I've typed into text fields on web-pages. I want to disable this but the only option I can find "Inline Autocomplete" is not checked in the advanced settings list.
Why is it doing it and can I stop it? If nothing else, its it possible to uninstall IE (and reinstall again perhaps, FF is my default browser ) or is it too integral to my OS?

Click on Internet Options, Content, Autocomplete, and then uncheck all the tabs to disable it.You can also click on Clear Forms if you want to erase those that were stored.

Cool, thanks a lot.
