How to clear your cookies
in Internet Explorer, posted Oct 22nd 2011
When you clear your cookies in Internet Explorer, all data that is saved by webpages onto your system will be erased. For example, if you selected for a website to automatically log you in, it will no longer do that since your login information is no longer stored in that specific cookie. However, clearing your cookies is a good way to speed up your system, since you likely have thousands of irrelevant cookie files saved onto your computer's hard drive, and they may be used by third parties to track your activity on the web.
To clear cookies in Internet Explorer, click on the Tools button (the button with the gear icon on the top-right corner), and then select "Internet Options".
After the "Internet Options" dialog appears, click on the "Delete..." button on the "Browsing history" subsection.
This will bring the "Delete Browsing History" dialog; once there, check the "Cookies" option (the "Temporary Internet files" option is checked by default, which will also clear your cached files). Finally, click the "Delete" button to clear your cookies.
