Mattias Fors has a post with a PowerShell script that can be used to download all Microsoft Ignite 2016 slide decks. The blog post is here: https://deploywindows.info/2016/09/30/download-ignite-2016-slidedecks,
You can use this script to download all the Azure Stack session decks.
Just change if ($item.title –notlike “Re:*”) to if ($item.title -like “*Azure Stack*”) in the script and run it. It will place them in C:\Ignite2016Slidedecks.
Enjoy!
