Hi, this way of installing is no longer working on Windows Server 2012 RTM. Here is a script that works for us:

function Install-WSUS {

param(

[switch]

$ContentLocal,

[string]

$ContentDirectory = "C:\ProgramData\WSUS\Content"

)

Install-WindowsFeature -Name updateservices -IncludeManagementTools

# Modification of the UpdateServices-Services.xml

# NOTE :

# When the installation is made with the previous cmdlet "Install-WindowsFeature ..." and not with the ServerManager GUI the XML configuration file UpdateServices-Services.xml is not correctly set.

# We need to set the value of the two properties : ContentDirectory and ContentLocal

invoke-command -ScriptBlock {
