                '[WindowsFeature]UpdateServices'

            Ensure = 'Present'
            ContentDir = 'C:\WSUS'
            Languages = @('en','fr')
            Products = @(
                'Windows Server*'
            )
            Classifications = @(
                'E6CF1350-C01B-414D-A61F-263D14D133B4', #CriticalUpdates
            )
            SynchronizeAutomatically = $true
