Right click the START button and choose EXPLORER.
The START MENU dialog box will appear as a vertical paned window.
On the right side you will see a file "tree" of choices, look for and click COOKIES.
Once you click COOKIES, look on the right side of the paned window.
There you will see a list of files that look little notepads.
Delete eveyone of them except the file that is labeled INDEX.
After having done that, if you have Internet Explorer, or any other browser, open it up.
Once your browser is open, om the MENU bar, click on TOOLS on choose INTERNET OPTIONS, at the bottom of the list.
An INTERNET OPTIONS dialog box will appear. In the center of that dialog box you will see a section called TEMPORARY INTERNET FILE.
In this section you will click on the slection that says DELETE FILES.
