Amazing script, this is for converting VHD's but it is an amazing reference, even build a GUI: http://www.ms4u.info/2012/06/create-sysprep-vhd-and-vhdx-for-windows.html (actual script http://gallery.technet.microsoft.com/scriptcenter/Convert-WindowsImageps1-0fe23a8f)
  1. How to even create and run a script file http://technet.microsoft.com/en-us/library/ee176949.aspx
    1. Basically enable local script execution with Set-ExecutionPolicy RemoteSigned
    2. Always run scripts with either their full path c:\test\script.ps1 or with .\ if in local directory .\test.ps1
      1. If path to script has space in it, must surround with double quotes and also must start with & sign &"c:\my scripts\test script.ps1"
    3. Example Script
test.ps1 
# Example of PowerShell Loop
echo ""
echo "Simple Foreach"
echo "--------------"
$NumArray = (1,2,3,4,5,6,7,8,9,10,11,12)
Foreach ($Item in $NumArray) {$Item * 13}

echo ""
echo "Split Path Variable"
echo "-------------------"
$a = $env:path; $a.Split(";")

# Any variable used in the script is local to that script, when the script is done any variable cannot be access by the shell unless you start the script with a . . ./test.ps1 or . &"c:\my scripts\test.ps1". Now any variable used in the script is accessible in the shell, just type the variable $var1 will print its contents, to remove it Remove-Variable var1 no $ sign.
# Run a script from CMD or Run command, powershell.exe -noexit dir c:\ or powershell.exe -noexit &"c:\my scripts\test.ps1"
# Run from vbscript
Set objShell = CreateObject("Wscript.Shell")
objShell.Run("powershell.exe -noexit c:\scripts\test.ps1")
