This post explains how to manually add or import updates into WSUS from Microsoft Update catalog.
But the first question that comes in mind is why do I need to manually import or add windows updates into WSUS ?. Can’t I simply run manual synchronization in WSUS console and download the update.
Well, sometimes the Microsoft hotfixes and updates are not part of WSUS catalog. So even if you synchronize the updates, you may not see those updates in WSUS console. Therefore you need to import the update manually from Microsoft Update Catalog.
To install and configure WSUS on Windows Server 2019, you can refer this post.
Manually Import Updates into WSUS
Use the below procedure to manually import updates in WSUS. As an example, I will be importing update KB4554364 into WSUS. This update is applicable for computers running Windows 10 1903 and Windows 10 1909 OS.
Launch the WSUS console, expand your server and click Updates. On the right pane, under Actions section, click Import Updates.
Clicking Import Updates opens the browser and takes you to Microsoft Update Catalog site. In the text box, type the update number which is 4554364 in our case and click Search.
Since the 4554364 is applicable to Windows 10, Windows Server etc, you must select the right OS version. From the list of updates displayed, read click Add button.
Clicking Add button adds the update to a basket. Click View Basket.
You can now click Import button. This will import the selected update directly into Windows Server Update Services.
You can monitor the import progress on this window. If the Progress shows Waiting, it means the import operation has begun.
Finally after few minutes, the progress is changed to Done. Click Close.
Let’s check if the update has been added in WSUS. In the WSUS console, click Search. In the Search box, type the update number and click Find Now. You can now see we have successfully imported the update into WSUS.
