Today I want to feature a really cool little PowerShell Script to download your favorite content from Microsoft Channel 9 @CH9.

As I do most days at lunch I scour the internet for great IT News, Blog Posts, and cool tricks to help me with my day job.

Today I was browsing my friend Vlad Catrinescu’s @vladcatrinescu blog: https://absolute-sharepoint.com/ and I found this amazing post…

https://absolute-sharepoint.com/2017/05/the-ultimate-script-to-download-microsoft-build-2017-videos-and-slides.html

Basically, it can be used as a downloader for any Channel 9 content from Microsoft. Sometimes it is nice to have offline content for when you are on the plane and this one really does the trick.

Now the code you see below is slightly modified as I thought it would be cool to download all the @MVPDays 2017 content.

You can download my modified version of the script from our MVPDays Github Repository. www.github.com/mvpdays
