One of the easiest customizations you can do to Internet Explorer is to change your home page. Your home page is the page that loads when you first open your browser. It is also the page that will show when you click your home button. Generally it should be a page that you think you will use the most. For example you may want to use Google since many people like Google’s search engine.
The easiest way to change your homepage is to open Internet Explorer, go to Tools, and then Internet Options. The General tab should be displayed as shown in the image below. In the Address box you can type in your new home page and then click OK. That’s it
