This policy setting allows you bypass prompting when scripts running within the Internet Explorer process attempt to perform a clipboard operation (for example, cut, copy, and paste) and the URLAction for the zone is set to prompt.

If you enable this policy setting, a script running in the Internet Explorer Process can perform a clipboard operation without prompting. In the internet explorer process if the zone behavior is currently set to prompt it will be bypassed and enabled.

If you disable this policy setting, the script cannot bypass the prompt for cut, copy or paste operations from the clipboard in the internet explorer process.

If you do not configure this policy setting, current values of the URL Action for the internet explorer process will prevail.
