This policy setting allows you to turn off the Data Execution Prevention feature for Internet Explorer on Windows Server 2008, Windows Vista with SP1, and Windows XP with SP3.
If you enable this policy setting, Internet Explorer does not turn on Data Execution Prevention on platforms that support the SetProcessDEPPolicy function.
If you disable or do not configure this policy setting, Internet Explorer uses the SetProcessDEPPolicy function to turn on Data Execution Prevention on platforms that support the function.
This policy setting has no effect if Windows has been configured to enable Data Execution Prevention.
