How can I clear ALL history of visits to Internet sites, not just delete them but clear the imbeded record?

I use Internet Explorer>Tools>Internet Options>General to "Clear History" but Google Desktop search indicates thousands of Internet visitations and this must be slowing my laptop. I would like to eliminate them from my memory. I would prefer not having to purchase a commercial Cleanser Program.... show more I use Internet Explorer>Tools>Internet Options>General to "Clear History" but Google Desktop search indicates thousands of Internet visitations and this must be slowing my laptop.
