The Yahoo homepage offers several customization options, including the ability to add links to other Yahoo services and other bookmarks. You can also add new sections to the main page to customize the types of news that you wish to see there. However, Yahoo doesn't provide any undo functionality so you can't compare your unchanged Yahoo homepage with your new Yahoo homepage. Create a duplicate homepage on Yahoo using Internet Explorer so you can make quick comparisons by simply changing tabs.
Click the "Start" button and type "Internet Explorer" in the Search Programs and Files text box. Click "Internet Explorer" in the search results to launch the browser.
Click the Internet Explorer address bar and visit the Yahoo homepage.
Right-click the Yahoo tab and select "Duplicate Tab" to create another tab that has the Yahoo! homepage.
