Remove computer object from Windows Server Update Services (WSUS) in PowerShell

Here is a short PowerShell snippet for you to remove a computer object from Windows Server Update Services (WSUS). In an elevated PowerShell session, adjust the following to your environment and execute:

$WSUS_server = 'wsus-srv-01'
$UseSSL = $True
$Port = 8531

[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | Out-Null
$Wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($WSUS_server,$UseSSL,$Port)

$client = $wsus.SearchComputerTargets("srv-01")
$client.delete()

This removes the server named “srv-01” computer object from WSUS on host wsus-srv-01.
