Hi,
As per description of the Group Policy setting "Include updated website lists from Microsoft" on GPMC console, by disabling this setting, the Microsft-provided lists are not used and the user will not be able to activate the feature.
If you disable the setting under "Policies\Windows Components\Internet Explorer\Compatibility View\Include updated Web site lists from Microsoft" the checkbox is detached but it is not greyed out.
I have tried to set the policy under Computer Settings, User setting and also making a Registry edition under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Internet Explorer\BrowserEmulation by setting "MSCompatibilityMode" to "1" but the behaviour is still not the desired.
Does anybody know if there is any way to grey out this setting?
