Modifying PowerShell script to export to .CSV for the computer within specific OU

Last Modified: 2016-03-02

Can anyone here please assist me in modifying the below powershell script so that it can be exported to CSV script for easy sorting ?

# This script shows the last time that a successfull Windows Update was installed.
add-PSSnapin quest.activeroles.admanagement
$OnlineServers = @()

Get-QADComputer -SearchRoot 'domain.com/Terminal Servers/Production 1' -OSName "Windows*Server*" | where {$_.accountisdisabled -eq $false} | % {
  $PingResult = Get-WmiObject -Query "SELECT * FROM win32_PingStatus WHERE address='$($_.Name)'"
  If ($PingResult.StatusCode -eq 0) {
     # Add the current name to the array
    $OnlineServers += "$($_.Name)"

foreach ($Server in $OnlineServers ) {
		$key = "SOFTWARE\Microsoft\Windows\CurrentVersion\WindowsUpdate\Auto Update\Results\Install"
		$keytype = [Microsoft.Win32.RegistryHive]::LocalMachine
		$RemoteBase = [Microsoft.Win32.RegistryKey]::OpenRemoteBaseKey($keytype,$Server)
		$regKey = $RemoteBase.OpenSubKey($key)
		$KeyValue = $regkey.GetValue("LastSuccessTime")
		$System = (Get-Date -Format "yyyy-MM-dd hh:mm:ss") 
		if	($KeyValue -lt $System)	{
			Write-Host " "
			Write-Host $Server "Last time updates were installed was: " $KeyValue

Open in new window


Feel free to replace the Get-QADComputerr with the builtin Get-ADComputerAccount and use Test-Connection instead of the existing convoluted way of doing it.

Ideally the exported result can just be:

ComputerName, last time windows updated, what KBnumber applied if possible.

Thanks in advance,
