In this article I have collated a few training links about Windows PowerShell. I will keep adding to this page as I find other useful free resources. If you have any videos or articles that you feel would be useful here then please let me know in the comments and I will add them to the post. I would like it to be an archive of good material.

Reblogged this on Bringing All The Fail and commented:
I’m selfishly reblogging this because it’s an awesome collection of resources and I don’t want to lose track of it and/or forget about it like I probably would if I just bookmark it. The timing on the article seems perfect since, while I’m quite proficient with PowerShell, I was just discussing with a coworker yesterday that I want to start getting into using C# to write my own cmdlets. I’ll have to brush a little rust off of my C# skills, though.
