Overview

WSUS can be a life saver, but with the large volume of updates that are put out from Microsoft, WSUS can grow out of control quite easily. To keep it under control you need to run the "WSUS cleanup wizard" periodically to keep things in good running order.

Run this PowerShell script as a Scheduled Task to keep your WSUS server slim and trim.

$outFilePath = '.\wsusClean.txt'
[reflection.assembly]::LoadWithPartialName("Microsoft.UpdateServices.Administration") | out-null
$wsus = [Microsoft.UpdateServices.Administration.AdminProxy]::GetUpdateServer();
$cleanupScope = new-object Microsoft.UpdateServices.Administration.CleanupScope;
$cleanupScope.DeclineSupersededUpdates = $true
$cleanupScope.DeclineExpiredUpdates = $true
$cleanupScope.CleanupObsoleteUpdates = $true
$cleanupScope.CompressUpdates = $true
#$cleanupScope.CleanupObsoleteComputers = $true
$cleanupScope.CleanupUnneededContentFiles = $true
$cleanupManager = $wsus.GetCleanupManager();
$cleanupManager.PerformCleanup($cleanupScope) | Out-File -FilePath $outFilePath

PowerShell

Before you can run this script as a Scheduled Task you need to do a few things:

1. Save it as a file with a .PS1 extension
2. Enable Script Execution by running the following command from within PowerShell

Set-ExecutionPolicy RemoteSigned

Also when you setup the task run it like this:

powershell.exe C:\Scripts\WSUS-Cleanup.ps1

You need to pass the full path to the .PS1 file.
It also has to be run with elevated privileges.
