Today I completed the Microsoft Virtual Academy Advanced Tools & Scripting with PowerShell 3.0 Jump Start course. If you haven’t looked at it yet, I realy recommend you do so, lots of good stuff there. So for the purpose of applying some of the stuff I’ve learned there regarding the use of -Whatif and -verbose messages i wrote the below script which downloads the sysinternals tools.
