Presentation and demo material - An Introduction to PowerShell
Thank you to those of you who attended the Powershell session at the December 2007 Premier Briefing event in Melbourne Australia. I hope you found the session informative. I have attached the presentation slides and the demo script I used on the day. It is actually an updated version of the presentation I delivered at TechEd 2007. I ran the demo script using Jeffrey Snover's "start-demo" script which you can find here https://blogs.msdn.com/powershell/archive/2007/06/03/new-and-improved-start-demo.aspx, although it's not needed if you just want to see the commands that we ran on the day. Please contact me if you would like more information.
Thanks.
Chris.
