Startup and Shutdown Settings

The Startup and Shutdown pane of Virtual Machine Configuration allows you to define a number of parameters related to the procedures of starting and shutting down your virtual machine.

In this pane, you can configure the following parameters:

If the Window or Full Screen or Coherence option is selected, the virtual machine will automatically switch to the specified view mode . If the Same as last time option is selected, the virtual machine will start in the same mode that was applied to it before it was turned off.
• The On application start option defines the operation to be performed on this virtual machine when you start Parallels Workstation Extreme.
  • Select Start/Resume if you want your virtual machine to start automatically every time you start Parallels Workstation Extreme.
  • Select Do Nothing if you do not want your virtual machine to start automatically when you start Parallels Workstation Extreme.
• The On application exit option defines the operation to be performed when you close Parallels Workstation Extreme:
  • Select Suspend if you want the virtual machine to be suspended when you close the application.
  • Select Stop if you want the virtual machine to be shut down when you close the application.
  • If you select Ask me what to do , you will be prompted to choose the operation to perform with the virtual machine each time you close Parallels Workstation Extreme.

Undo Disks

The Enable Undo Disks option allows you to discard or apply the changes you made to the virtual machine's hard disk during your working session. If you choose to discard them, the changes will be discarded when you shut down the virtual machine. When you start this virtual machine again, its virtual hard disk will have the same data it contained before you started the previous working session. If you choose to apply the changes on the virtual machine shutdown, the next time you start this virtual machine, its virtual hard disk will store the changes you made during the previous working session.

Note: When enabled, the Undo Disks feature is applied to all virtual hard disks this virtual machine uses.

You can choose whether you want to discard the changes you made to the virtual machine's hard disk or choose the action to perform in the On shutdown field.

• Discard changes . Select this option if you want to discard the changes when you shut down this virtual machine.
• Ask me what to do . If this option is selected, you will be prompted to choose the action to perform with the changes (discard or apply them) each time you shut down the virtual machine.

Note: You cannot create snapshots of virtual machines that have this option enabled.
