Companies that provide Internet access to end users can force the browser's homepage by editing the Windows registry. The default homepage is the Web page that appears each time the user opens the browser. The Windows registry contains the settings and configurations for the software and hardware installed on the machine. Updating the registry with a default homepage can be done using the "Regedit" tool.
Click the Windows "Start" button and select "Run." In the text box shown, enter "regedit" and press the "Enter" key. This opens the Windows registry editor.
Navigate to the "HKEY_LOCAL_USER\Software\Microsoft\Internet Explorer\Main" registry key. Within this directory, click the key labeled "Main."
Right-click the "Main" registry key, select "New," and then choose "String Value." This creates a new registry key.
Enter "Default_Page_URL" in the key's "Name" text box. In the "Value" text box, enter the homepage you want to use for all the users who use the computer. Press "Ok" to save the changes.
Reboot the machine for the changes to take effect. Changes to the registry do not take effect until the computer is reboot.
