How to Change the Homepage From Yahoo to Google
Your homepage appears when you open your Web browser or click the "Home" icon on its toolbar. The homepage is defined in your Web browser's options window. If the Yahoo search engine is your current homepage, you can change it to another Web page such as Google. After you change it, Google will appear each time you open your Web browser, allowing you to perform Google searches without navigating to Google.com first.
