What is Exclusive Mode in VMWare?

Exclusive mode changes two things:

  1. It gives the guest control over the system display resolution(s).
  2. It removes any VMWare "toolbars" and such -- it makes the guest OS behave as if it were the OS, rather than a full screen guest. You don't have to worry about the guest losing focus if exclusive mode is on, other than the "Secure Attention Sequence/Three Finger Salute/Ctrl+Alt+Del" and the "breaking key combination" you set (which is Ctrl+Alt by default).
