Import the convenience update into WSUS

My WSUS server runs on a Windows Core edition where I don’t have Internet Explorer installed.

Whatif I want to import the Convenience rollup update for Windows 7 SP1 and Windows Server 2008 R2 SP1 from the catalog?

Here’s the way to go:

On a client computer with a GUI, launch internet explorer with high privileges to be able to install the ActiveX.

$HT = @{
 FilePath = 'C:\Program Files (x86)\Internet Explorer\iexplore.exe' ;
 ArgumentList = 'http://catalog.update.microsoft.com/v7/site/Search.aspx?q=KB3125574' ;
 Verb = 'Runas'
}
Start-Process @HT

MS-catalog-ActiveX-install

Install the ActiveX, add the update to the basket, view your basket, download, browse…
Move the file onto the WSUS server…and check if the file is digitally signed

Get-AuthenticodeSignature -FilePath ~\downloads\Catalog\*\*.msu

The WSUS API has an ImportUpdateFromCatalogSite, documented here on msdn.
WSUS-import-method

I’m missing the UpdateID. Where do I find this Id?

It appears that if you click on the link highlighted below…

MS-catalog-KB-link

…you get on a page where you’ve more details about the update.

Convenience-update-Id

The updateId actually appears in the address bar. 😀

Now, to import the update into WSUS, I do:

$MSUfile = 'C:\Users\administrator\Downloads\Catalog\Update for Windows 7 for x64-based Systems (KB3125574)\AMD64-all-windows6.1-kb3125574-v4-x64_2dafb1d203c8964239af3048b5dd4b1264cd93b9.msu'
(Get-WsusServer).ImportUpdateFromCatalogSite(
    '49924c88-1b31-4b0f-ad3d-48df9877f385',
    $MSUfile
)
# Find the imported file
(Get-WsusServer).SearchUpdates('3125574') | fl *

The convenience update has been successfully imported and can now be approved.
