Notes and Concerns: (Windows XP Mode SHOULDN'T BE USED ON THE INTERNET!!)
-----------------------------------------------------------------------------
  a.  The floppy disk is listed as "A:", but the USB floppy drive is actually
      at the mapped drive "A on <computer user logged>" which has a path of
      "\\tsclient\A\"
  b.  Multiple floppies in sequence will not load past floppy disk 1.
  c.  Windows XP Mode has no Anti-Virus and probably needs one.
  d.  Printer drivers must be installed.
  e.  Access to folders and drives in the Windows 7 environment is possible
      but it is not assumed to have a path back to Windows XP Mode also.
      Windows XP Mode appears to be only partially sandboxed and may have
      serious security flaws.
  f.  Windows XP Mode uses Internet Explorer 6 (default) that should be
      upgraded to Internet Explorer 8.  (Internet Explorer 9--to be released--
      will not work with Windows XP and probably won't with Windows XP Mode.
  g.  All the security updates past SP3 default of Windows XP Mode appear to
      be missing--a real security swamp with alligators!
