Again, here's my entry for the Beginner Event 3 before I read the expert commentary.

<#
 .Synopsis

 When run it will create a text file listing the running Process Name and ID.

Param([string]$ResultsRoot,[string]$ComputerName)

$FileLocation=""

If($ResultsRoot)
{
 $FileLocation=$ResultsRoot

 If($ResultsRoot.Substring($ResultsRoot.Length-1) -ne "\")
 {
  $FileLocation+="\"
 }
}
else
{
 $FileLocation=$env:SystemDrive
 $FileLocation+="\"
}

If(!$ComputerName)
{
 $ComputerName="localhost"
}

$FileLocation+="\2012SG\event3\"

Function Check-Path
{
param($Location, $TypeOfPath)
 If(!(Test-Path $Location))
 {
  New-Item -Path $Location -ItemType $TypeOfPath
 }
}

Check-Path $FileLocation "directory"
$FileLocation += "process3.txt"
Add-Content $FileLocation (Get-Process -ComputerName $ComputerName | Format-Table -Property "ProcessName","ID" -AutoSize | Out-String) 

I've made a mental note to look for a way to make PS scripts look nicer in the blog. Done...a bit. :)

UPDATE:

Looking at the expert commentary, I would've lost a point or two for not putting any error handling in the Check-Path function.  The expert setup error handling and then went one step further to default to the current users "My Documents".  Also, I needlessly added the "ComputerName" element.

At least I didn't fall for the hardcoded "C:\" trap that was set :)
