Unable importing updates on WSUS 5.0 from Microsoft Update Catalog

Windows Server

Bad news for all Windows Server 2016 owners because there’s a strange errors that deny the manual import of updates from Microsoft Update Catalog. The message error is “This update cannot be imported into Windows Server Update Service because it is not compatible with your version of WSUS” – figure 1.


Figure 1 – Import Error


Product team is working on that, but in the meantime this is the workaround:


  • After clicking on the “Import Updates…” option in the WSUS console, an Internet Explorer window will open on the following URL: http://catalog.update.microsoft.com/… &Protocol=1.20
  • Before proceeding with importing the updates, change the “1.20” protocol value in the URL to the previous protocol value “1.8”. The URL should look like this when you’re done: http://catalog.update.microsoft.com/… &Protocol=1.8
