Q: What new Group Policy settings are available for Internet Explorer 10 or Internet Explorer 11?
A: The easiest way to check what new Group Policy options are available for anything is to download the latest version of Microsoft's Group Policy reference Excel spreadsheet. Once it's downloaded, open the spreadsheet and navigate to the section you care about.
For example, look at inetres.admx for Internet Explorer, in column G, Supported On. The Supported On column will show you the version of Internet Explorer that the policy is supported on. Look around the spreadsheet; it gives great information on all the new settings.
