DTBI116-IE11 - ActiveX controls marked safe for scripting must be disallowed (Restricted Sites zone).
This policy setting allows management of whether ActiveX controls marked safe for scripting can interact with a script. If you enable this policy setting, script interaction can occur automatically without user intervention. ActiveX controls not marked as safe for scripting should not be executed. Although this is not a complete security measure for a control to be marked safe for scripting, if a control is not marked safe, it should not be initialized and executed.
Set the policy value for Computer Configuration -> Administrative Templates -> Windows Components -> Internet Explorer -> Internet Control Panel -> Security Page -> Restricted Sites Zone -> 'Script ActiveX controls marked safe for scripting' to 'Enabled', and select 'Disable' from the drop-down box.
