As noted earlier, Truesec is now offering video training for CM2012. If you’re just not sure about the training, or haven’t had time to delve too deeply into the offering yet, there’s now a free sample available for you to view. The free session is about deploying Windows 7 using MDT 2012 and CM2012.
