Example 1: Out-GridView -PassThruPowerShell 3.0 Passthru Parameter

Let us take this example where we are using PowerShell 3.0 to display the processes.

Get-Process Out-GridView -PassThru 

The benefit of the -PassThru parameter comes when you select rows with the mouse, and then click OK.  The result is that PowerShell refreshes the output. 

Take the screenshot to the right where I have selected just 5 rows,  dlhost, LogonUI, lsass, MsMpEng and SearchIndex.  When I pressed ‘OK’, the result was a display with just those 5 rows.

Result of -PassThru and pressing ‘OK’

Simple Example of -PassThru

Here is an example where you want to rename a Windows computer.

# PowerShell 3.0 Rename-Computer with -PassThru
$Old ="OriginalName"
$New ="GuyServer"
Rename-Computer -NewName $New -ComputerName $Old `
-PassThru -WhatIf

Note 2: To get this working you need to change $Old to the value of your machine; don’t worry the -WhatIf will stop this actually renaming this computer.

Launching PowerShell v 3.0PowerShell 3.0

This is how to get started from the Metro user interface in Windows 8.

  • From anywhere in the Metro UI, press the ‘p’ key.  You should see a list of the programs and Apps beginning with ‘p’.
  • At this point you could ‘Pin’ the ‘Windows PowerShell ISE’ by right-clicking and selecting ‘Pin’ at the bottom right of the screen.
  • Incidentally, I prefer the GUI (ISE) version to the plain command line Windows PowerShell.
  • I like to drag the PowerShell ISE tile to the left of my screen because it’s one of the most important Windows 8 Tiles that use.
