WSUS, Automatic get rid of Itanium Updates nobody needs in 2013

by butsch 5. July 2013 04:09

WSUS-Admins who take care of their WSUS Server and run the box over a few years know why to sort

Out updates which you don't need. Esp. when you run on SQL Express. Yes you can shrink, yes you can migrate

But it gets slow. So best practive is to decline the "superseded updates" or updates which are quite old.

Also the "Itanium" updates which some guy at a university and bill gates in his garage still use.


If you run the script without chaning the Signung policy of your 2008R2 or maybe also 2012?

(Notice the .\scriptname!)

Change the red parameters to your WSUS-Server, Check in IIS (Internet Information Server) which Port your WSUS uses


$WsusServer = ""

$UseSSL = $false

$PortNumber = 8530

$TrialRun = $true

# $TrialRun = $false (To actually do it)


[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null

$WsusServerAdminProxy = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer($WsusServer,$UseSSL,$PortNumber);


#$itanium = $WsusServerAdminProxy.SearchUpdates('Itanium') | ?{-not $_.IsDeclined}

#$itanium += $WsusServerAdminProxy.SearchUpdates('ia64') | ?{-not $_.IsDeclined}

#Although the above seems faster it also seaches in the description of the update so use the below just to search the title!

$itanium = $WsusServerAdminProxy.GetUpdates() | ?{-not $_.IsDeclined -and $_.Title -match "ia64|itanium"}

If ($TrialRun)

{$MessageSubject += " Trial Run"}


{$itanium | %{$_.Decline()}}
