Powershell Scripts for IT Support

I just started a new project at work.
Finding and creating useful Powershell scripts for IT Support.
My Problem is to find good sources who explain this for me.
So I bought me two books for self study.

I will start with some easy scripts and continue with more powerful ones.

Actually I have a problem to create scripts for Windows 7 and PS 2.0 .
It’s so much easier to create PS 3.0 scripts but most of the clients are actually Windows 7.

So if I finished some of these scripts, you will find them in the tutorials section.

If you have good sources for PowerShell Scripts or selfstudy websites, please leave me a comment.
