How to set the Internet Explorer Home Page via GPO?

There are a few different ways to do it. Do you want to force everyone's home page, and disallow changes? Or do you just want to set a default home page that people can modify?

If you want to force a home page: 

• Create a new GPO or edit the existing one.
• In the Group Policy Management Editor, go to User Configuration -> Policies -> Administrative Templates -> Windows Components -> Internet Explorer.
• Find the policy Disable changing home page settings.
• Set it to Enabled, and specify the URL for your home page.
• Once it applies, the option in IE will be grayed out on the client PC.

If you want to specify a default that people can change:

• My preferred method would be to use Group Policy Preferences to set the necessary Registry values. (Others may disagree.)
• In the Group Policy Management Editor, go to User Configuration -> Preferences -> Windows Settings -> Registry.
• Right click -> New -> Registry Item
• Action = Update
• Hive = HKEY_CURRENT_USER
• Key Path = Software\Microsoft\Internet Explorer\Main
• Value Name = Start Page
• Value Type = REG_SZ
• Value Data = your Home Page URL
• On the Common Tab, check Apply Once and Do not Re-Apply
• This will set the home page by default for everyone, but the user will be free to edit it afterwards.
• If you go this route, I also recommend that you set a value for Default_Page_URL as well,without checking Apply Once and Do not Re-Apply. This will give your users the ability to click the Use Default button in the IE settings and get back to the company home page.
• You probably also want to delete the Secondary Start Pages and Default_Secondary_Page_URL registry values as well.
• If you are unfamiliar with these registry values, it would probably be a good idea to open the Registry Editor and look at HKCU\Software\Microsoft\Internet Explorer\Main to understand how they work.
