PowerShell labcast
There is a PowerShell labcast available from
https://www.microsoft.com/resources/virtuallabs/step1-technet.aspx?LabId=f7c0553e-78ee-4514-a9aa-097b673be3a7
Some one who tried it reports:
"It has a few quirks – on one occasion the voice-over disappears for a few minutes. If you leave the labcast and return to it later, your VM (and your work) is gone, so best done in a single session – or do the labwork on your local machine. Exposure to other scripting tools will help – most of the concepts transfer."
