PowerShell Pre-requisites and Checklist
In the case of Windows 7 and later, you don't need to download any extra files, just: 'Add Feature' --> Windows PowerShell. However, for older operating systems, there are different versions of PowerShell for XP, Windows Server 2003 and Vista. For such legacy systems only, you need to download PowerShell from Microsoft's site.

Simple Scenario: We want to examine the properties of Windows services. The technique is to first export the data, then import and finally, apply Get-Member.

Note 1: One reason that I have used a variable to control the path, is that I want to remind you to change its value before you run this script on your machine.

Note 3: Save Frustration

SolarWinds' Network Performance Monitor will help you discover what's happening on your network. This utility will also guide you through troubleshooting; the dashboard will indicate whether the root cause is a broken link, faulty equipment or resource overload.
What I like best is the way NPM suggests solutions to network problems. Its also has the ability to monitor the health of individual VMware virtual machines. If you are interested in troubleshooting, and creating network maps, then I recommend that you try NPM now.
Import-CSV Has an Alias Called IpCsv
With Microsoft, there are always at least three ways of doing everything, what seems like redundancy when you are an expert, seems like perspective when you are a beginner. One obvious example is that you can abbreviate Format-Table to ft. As you increase your range of PowerShell commands, keep an eye out for another PowerShell Alias, for example gci (Get-Childitem).
