Lately i get a lot of questions about the ability (or inability) of editing internet explorer 10 or 11 settings with domain GPO.
Microsoft decided to deprecated old Internet Explorer Maintenance (IEM) in favor of more robust tools like Group Policy Preferences (GPP), Administrative Templates (.admx), and the Internet Explorer Administration Kit 11 (IEAK 11).
Because of this change, any settings that you previously configured with IEM will no longer work on computers where Internet Explorer 10 or newer is installed, regardless of the Windows version it’s been installed on. You must update your settings using Group Policy Preferences, Administrative Templates (.admx), or the Internet Explorer Administration Kit (IEAK).
