Tagged: PS Remoting COM object

I'm trying to configure Windows Update Setting on a remote computer using:
$WUSettings = (New-Object -com 'Microsoft.Update.AutoUpdate').Settings $WUSettings.NotificationLevel = 3 # Download Updates but let me choose whether to install them $WUSettings.save()
which works just fine when logged in locally to the computer. For example, I can view the settings by:
(New-Object -com 'Microsoft.Update.AutoUpdate').Settings
and I get:
NotificationLevel : 3 ReadOnly : False Required : False ScheduledInstallationDay : 0 ScheduledInstallationTime : 3 IncludeRecommendedUpdates : False NonAdministratorsElevated : True FeaturedUpdatesEnabled : False
The problem is the same exact code does not work when in a remote PowerShell session. Both source and target computers are Windows 2012 R2 server with PS 4 running.
When I try to run the same commands in a PS remote session I get:
[10.121.111.68]: PS C:\Users\Administrator\Documents> New-Object -com 'Microsoft.Update.AutoUpdate' -Verbose Settings ServiceEnabled Results -------- -------------- ------- System.__ComObject
Nothing under 'Settings'. Subsequently $WUSettings.save() fails since $WUSettings is now a null object and does not have the save() method.
I validated that the PS remote session is running under the local administrator account and is elevated:
[10.121.111.68]: PS C:\Users\Administrator\Documents> $identity = [Security.Principal.WindowsIdentity]::GetCurrent() $principal = New-Object Security.Principal.WindowsPrincipal $identity $principal.IsInRole([Security.Principal.WindowsBuiltinRole]::Administrator) True [10.121.111.68]: PS C:\Users\Administrator\Documents>

I'm suspect that it (IAutomaticUpdatesSettings), just as IUpdateInstaller, can't be instantiated remotely
with IUpdateInstaller I solve it through task scheduler

Max – your suspicion is correct. You can't instantiate The Update COM objects through a emoting session. The CIM classes introduced in Windows 10/2016 do work remotely but the COM objects on older versions of Windows don't
