I understand that "IE Maintenance" in Group Policy (User Configuration-> Policies-> Windows Settings) has been retired in Server 2012 in favor of IEAK (Internet Explorer Administration Kit) because it does not support IE10.
We have IE9 in our production environment, and we are planning to upgrade them to IE10 in the future, but we have high restrictions through the group policy on IE9 settings (users are not able to change anything), so can we do the same thing with IEAK? or we have to do something else?
