Synchronize WSUS with Powershell

Yesterday, I showed you how to script the WSUS Cleanup Wizard with Powershell. Today, the WSUS fun continues! Here’s how to use powershell to “manually” synchronize your WSUS server, i.e. download the latest updates.

#Region VARIABLES
 
# WSUS Connection Parameters:
[String]$updateServer = "myWSUSServer.domain.local"
[Boolean]$useSecureConnection = $False
[Int32]$portNumber = 80
 
#EndRegion VARIABLES
 
#Region SCRIPT
 
# Load .NET assembly
[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
 
# Connect to WSUS Server
$Wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($updateServer,$useSecureConnection,$portNumber)
 
# Perform Synchronization
$Subscription = $Wsus.GetSubscription()
$Subscription.StartSynchronization()
 
#EndRegion SCRIPT

Download the script here: Synchronize-Wsus (rename to .ps1)

Enjoy!

WSUS Cleanup with Powershell

If you manage a Windows Server Update Services (WSUS) server, you probably run the Server Cleanup Wizard every once and a while. It removes old and superseded updates and computers that haven’t reported their status for more than 30 days. Wouldn’t it be nice to schedule such a cleanup to run every month? Too bad there’s no command line tool I know of that can help you out with this. Powershell to the rescue!
Powershell can not only run the built-in commandlets or even those added by snapins. It can leverage the full power of the .NET Framework. Browse the MSDN Library if you want to find more cool things you can do with it. Here’s a script that uses this information to run the cleanup wizard:

#Region VARIABLES
 
# WSUS Connection Parameters:
[String]$updateServer = "myWSUSServer.domain.local"
[Boolean]$useSecureConnection = $False
[Int32]$portNumber = 80
 
# Cleanup Parameters:
# Decline updates that have not been approved for 30 days or more, are not currently needed by any clients, and are superseded by an aproved update.
[Boolean]$supersededUpdates = $True
# Decline updates that aren't approved and have been expired my Microsoft.
[Boolean]$expiredUpdates = $True
# Delete updates that are expired and have not been approved for 30 days or more.
[Boolean]$obsoleteUpdates = $True
# Delete older update revisions that have not been approved for 30 days or more.
[Boolean]$compressUpdates = $True
# Delete computers that have not contacted the server in 30 days or more.
[Boolean]$obsoleteComputers = $True
# Delete update files that aren't needed by updates or downstream servers.
[Boolean]$unneededContentFiles = $True
 
#EndRegion VARIABLES
 
#Region SCRIPT
 
# Load .NET assembly
[void][reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration")
 
# Connect to WSUS Server
$Wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::getUpdateServer($updateServer,$useSecureConnection,$portNumber)
 
# Perform Cleanup
$CleanupManager = $Wsus.GetCleanupManager()
$CleanupScope = New-Object Microsoft.UpdateServices.Administration.CleanupScope($supersededUpdates,$expiredUpdates,$obsoleteUpdates,$compressUpdates,$obsoleteComputers,$unneededContentFiles)
$CleanupManager.PerformCleanup($CleanupScope)
 
#EndRegion SCRIPT

Download it here: Cleanup-Wsus (rename to .ps1)

Happy scheduling!
