Script to query OU for last Windows update date and time

Question

Hi All, I need help in writing a script which can query an OU in active directory and then return most recent date of windows updates installation. It will also be helpful if the script can sort the names and then send output to a file (any format will
do). I know basic of querying a local computer but not remote query, I am terrible at scripting side of powershell. Thanks people.

I am referring to the script below, how can I get the result to output in an XLS or CSV format, I tried couple of combinations but couldn't get it to work.# This script shows the last time that a successfull Windows Update was installed.clsadd-PSSnapin quest.activeroles.admanagement 
$OnlineServers = @() 
Get-QADComputer -SearchRoot 'domain.com/ServerOU'-OSName "Windows*Server*"| %{ 
  $PingResult = Get-WmiObject-Query "SELECT * FROM win32_PingStatus WHERE address='$($_.Name)'"If ($PingResult.StatusCode -eq 0)  
     # Add the current name to the array$OnlineServers+= "$($_.Name)" 
foreach ($Serverin$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
    }
