Hi LucD,
I have finally completed the below script to do windows updates on all templates in a datacenter using a DHCP vLan. Thanks for your support.
I need one fix in the script output. After updating windows I am writing output in a csv but that is not writing in correcting format. Every VMs output is written twice and leaving blank rows between every vms output. Sample output
Script:
$location=Get-Location
$CurrentDate = Get-Date -Format 'MM-dd-yyyy_hh-mm-ss'
$logfilelocation= "$location$($CurrentDate)logfile.txt"
$alltemplatesexportpath="$location$($CurrentDate)-templateswindows.csv"
$Outputfile = "$locationAllTemplatepatchstatusreport.csv as on dated $($CurrentDate).csv"
$csvFiles = @()
Write-Host "Enter Administrator Credentials for logging into templates" -ForegroundColor Yellow
$cred=Get-Credential
Start-Transcript -Path $logfilelocation -NoClobber -Force -Confirm:$false
$script = @'
$report = @()

$Error.Clear()
