Download and Install Windows Updates offline using the wsusscn2.cab file and Windows Update API
Hi, I'm trying to find a way to install Windows Updates (CAB files) on offline Windows 10 V1809 computers. Overall the process I'm trying to automate is: 1. Scan for missing Windows Updates on the computer and download all missing Windows Updates 2. On an offline computer - install the Updates. I'm using the wsusscn2.cab file as described here: https://learn.microsoft.com/en-us/windows/win32/wua_sdk/using-wua-to-scan-for-updates-offline to search the updates, download them, and then try to install them. I manage to search and download the updates, but I encounter this error when trying to install: When -2145124318 in Hex is: 0x80240022 This error code = WU_E_ALL_UPDATES_FAILED Operation failed for all the updates. How can I fix my code to successfully install this updates? Here is the code I'm using: #Search for Windows Updates: # Load the Windows Update Agent COM object $UpdateSession = New-Object -ComObject Microsoft.Update.Session $UpdateServiceManager = New-Object -ComObject Microsoft.Update.ServiceManager #Load the wsusscn2.cab file that enables offline Updates instllation: $UpdateService = $UpdateServiceManager.AddScanPackageService("Offline Sync Service", "c:\wsusscn2.cab") # Create a searcher for available updates $UpdateSearcher = $UpdateSession.CreateUpdateSearcher() # Search for updates in the SoftwareDistribution folder: #The ServerSelection enumeration defines values that describe the type of server to use for an update search operation. # ssOthers: Search another server, to be specified by other means $updateSearcher.ServerSelection = 3 # ssOthers $UpdateSearcher.ServiceID = $UpdateService.ServiceID $Criteria = "IsInstalled=0 and Type='Software'" $SearchResult = $UpdateSearcher.Search($Criteria) $Updates = $SearchResult.Updates if ($SearchResult.Updates.Count -eq 0) { write-Host "There are no applicable updates" } #Download the Windows Updates (to SoftwareDistribution): $SearchResult = $Updates # Create a Windows Update Session $Session = New-Object -ComObject Microsoft.Update.Session # Create a Windows Update Downloader: $Downloader = $Session.CreateUpdateDownloader() $Downloader.Updates = $SearchResult #Download updates to C:\Windows\SoftwareDistribution $Downloader.Download() #Install the Windows Updates from SoftwareDistribution: # Create the Installer Object: $installer = New-Object -ComObject Microsoft.Update.Installer $Installer.Updates = $Updates #Install updates: $Result = $Installer.Install() Thanks, Ann
