A. Microsoft has released a utility, which you can download here ,that deletes all temporary Internet files, cookies, and history files. After you download and run the files, click Next to the wizard's Welcome page. On the next screen, select "I Agree" and click Next. This program was initially intended to clear the cache in an error scenario, particularly around corrupt entries.
