This setting hides Properties on the context menu for Computer. If you enable this setting the Properties option will not be present when the user right-clicks My Computer or clicks Computer and then goes to the File menu. Likewise Alt-Enter does nothing when Computer is selected. If you disable or do not configure this setting the Properties option is displayed as usual.
