Disable "Connections" tab

You don't need to modify the registry. Start - Run type in gpedit.msc . In User configuration - administrative templates - windows components - internet explorer - internet control panel - double click on "disable the connections page" select enable and click ok. you may or may not have to log off and login to have the policy take effect. hope this helps.

This solutions requires to go to every computer - what I need is a .REG that can be pushed via login script.
