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.
