Microsoft rolls out “Lab”casts
What is a labcast? An online presentation with guided video demonstrations where you also get the chance to perform these same exercises on your own hands-on virtual lab that we provide during the session. As you face challenges in your lab, our instructors virtually take control of your lab to guide you through the tasks, giving you experience-based knowledge on the Microsoft product or topic. (There are no live instructors if you are watching an on-demand version.)
