To answer your question...
Go to your C Drive and click on a folder called "Documents and Settings". Once inside that folder, find a folder with your name or id and click it open. There are three folders you need to look for, "Favorites", "Cookies" and "Local Settings". In "Favorites" and "Cookies" you can delete all of the files in there. In "Local Settings" delete files in "History", "Temp" and "Temporary Internet Files". Don't forget to delete any files in "My Documents".
I hope this helps.
