In the Browsing history section, select Delete. Select the check boxes next to the files you want to delete.

Now that the files and cookies are gone, minimize their impact going forward. In the Internet Options menu, go to Browsing history > Settings. Next to Disk space to use, lower the amount of memory IE uses to store temporary internet files. Microsoft recommends you set this number between 50 MB and 250 MB. Select OK to save your changes.
