If Undo is enabled for the VM, you get just one snapshot to revert your
VM to its baseline state. VPC doesn't permit multiple snapshots to
capture changes to a VM, like you want to add Windows updates to bring
your OS up to a new baseline but sans any applications that you install
atop of it.
You might want to create a guest that is your baseline VM. You only
apply any changes, like updates, to it but don't install any apps on it.
That would be your "Reference" guest. You then create a new VM which is
your "Test" guest. When creating a virtual disk drive for the Test
guest, you make it a differential disk based on the .vhd file (the
virtual disk) from your baseline or Reference guest. You then load your
Test guest to install your apps and do you testing. You can revert back
to its baseline by "Turn off and delete changes"; however, if you ever
"accidentally" save the changes, you can't revert anymore. In that
case, you could delete the .vhd file for your Test guest and recreate
its virtual drive as a differential drive off your Reference guest's
