Use PowerShell to install Windows Updates in vSphere

Question

I have a cluster of vSphere windows clients approximately 100 that I want to remotely automate windows updates on weekly. I have listed all the windows machine out in text file on my desktop. I have run the PSWindowsUpdate module on my local windows10 machine with command:
Install-Module -Name PSWindowsUpdate and then executed the below script successful for my local machine to run windows updates.

#Import-Module PSWindowsUpdate
#Remove-Item -Path C:\Scripts\status.tx
#Start-Transcript -Path C:\Scripts\status.txt
#$Updates = "Critical Updates", "Security Updates"
#Get-WUInstall -AcceptALL- Verbose -IgnoreReboot -Category $Updates
#Write-Host "Done"
#Stop-Transcript
#Start-Sleep -s 120
#Restart-Computer -Force -Confirm:$false

-- after pc restarts run as PS As Administrator #Get-WindowsUpdate

However, I am not a expert at PowerShell so, I do not know what to additionally script to accomplish the task of remotely updating 100 or so windows clients in vSphere.

Any suggestion would be appreciated.

You can try with the invoke-command. You can create a server list from a DC:

$Servers = (Get-ADObject -Filter * -Properties Name,OperatingSystem | Where-Object OperatingSystem -like ' Server ' )

and use this list with a loop like this

ForEach($_ in $Servers) { Invoke-Command -ScriptBlock {Get-WUInstall -AcceptALL- Verbose -IgnoreReboot -Category $Updates } -ComputerName $_.Name -ErrorAction SilentlyContinue }
