In the past I have been using Alcohol 120% or Daemon Tools to mount MSDN ISO images, but I was unable to get either of these tried-and-true utilities to work on the new Vista RTM.
The good news is I was able to get a program called CloneDrive working with no problems at all.
Nice sheep logo. I assume the sheep is an allusion to the genetic cloning thing. In any case, nice work to Elaborate Bytes AG, Cham, Switzerland for this free utility that actually works.
Virtual Sheep? Baahaaah.
