By selecting "Enable" in the drop-down box, VBScript can run without user intervention. By selecting "Prompt" in the drop-down box, users are asked to choose whether to allow VBScript to run. By selecting "Disable" in the drop-down box, VBScript is prevented from running. If this policy setting is not configured or disabled, VBScript will run without user intervention.
