Several people who attended my PowerShell talk at SPC09 have been asking for the “Start-Demo” Script I used to demo PowerShell commands without having to type them in front of a live audience.
The script I used is really just a slightly modified version of this one
iI recommend just using the version provided by the PowerShell team.
Also, I recommend pairing this with the Sysinternals tool ZoomIt to allow for zooming and underlining elements on the screen.
This is a free tool available from the Sysinternals website: http://technet.microsoft.com/en-us/sysinternals/default.aspx
