The following steps will walk you through clearing out the browsing history and cookies from Internet Explorer, in a way suitable for clearing a server before major software installation. Or, you might use these steps if you’re having trouble client-side and you need to be sure that you’ve retrieved the most recent version of a web application.

1. Launch Internet Explorer
2. 

   Click the image to show the full-size version in a new window.

   Click the Internet Options toolbar button, which has a grey-white Gear icon. That’s labelled with highlight “1” in this following image.

3. On the General tab, in the Browsing history section, click Delete… That’s labelled with highlight “2” in this image.
4. In the Delete Browsing History popup, make sure that the second three checkboxes are checked. Note: the topmost option starts out checked. You should un-check it. Those are indicated with highlight “3” in this  image.
5. Finally to commit these changes, click the Delete button in the Delete Browsing History popup, then OK in the Internet Options popup.
6. After a bit of a pause, the original Internet Explorer window should tell you with a message at the bottom of its window that the history has been deleted.
