To delete element in the Control Panel.

Dear TechRepublic: before I realized how Java installs updates, I got stuck two previous entries (icons) of old versions in the Control Panel. To get rid of them I need the corresponding unistall.isu files, which I do not have anymore and it is impossible for me to get. I did not manage by editing the Registry. Could you, please, help me to delete these elements from the Control Panel. Many thanks. Raul.
