Vista - HowTo: Disregard changes when closing

Using: MS VPC-2007-SP1

I'm having problems disregarding changes when I use VPC. I made some changes
with an XpPro-SP3 virtual machine, and then closed the VM. I was expecting
the changes to be ignored/disregarded, but when I restarted the VM, the
changes were still there.

IIRC, at one point there were multiple options when you clicked on the upper
right X to close the VM, including:
* Save state
* Close and save state
* Close and ignore changes
(don't remember exact wording, might have been a 4th)

I updated computers and re-install VPC-07-SP1, and am no longer seeing the
options above, but only the basic:

* Save state
* Turn off

Am I doing something wrong, or have a setting wrong?

I want to be able to start a VM, try something out, and then close the VM
and have all changes ignored / disregarded / thrown away.

What I'm doing now is saving a "master" of the "vanilla" VM of XpPro-SP3,
and copying it back as a way to "put everything back the way it was".

>Am I doing something wrong, or have a setting wrong?

You need to enable "Undo Disks" for that VM. It's in the VM's
settings and the VM has to be in a fully shut down state to change it.
