You can specify the URLs for the home, search, and online support pages.
Home page URL
The home page, sometimes known as a start page, appears when the user clicks the Home button. Internet Explorer can show a default home page, or you can specify a URL for your own page.
Type the URL for the home page that you want to use in the Home page URL box. If you want to use the Internet Explorer default home page, click Use Default.
Search bar URL
The Search bar appears in the Explorer bar on the left side of the screen. This bar enables a user to see the search query and search results at the same time. The Search bar comes with a choice of search engines. You can change the URL for this page if you want; for more information, see Customizing the Search Assistant.
If you want to use the Internet Explorer default Search bar, click Use Default.
Online support page URL
In Internet Explorer, support information is available by clicking Help, and then clicking Online Support. It's recommended that you develop a support page and make it available to your users.
Type the URL of your custom support page in the Online support page URL box. If you want to use the Internet Explorer default support page, click Use Default.
