Hi alelusi,
We have the way to import update and upgrade kb into WSUS. Following are the steps:
1.Open
the WSUS console
2.In the console tree, right-click the Updates section and select Import Updates

3.Then Internet Explorer will start and automatically go to Microsoft Update Catalog webpage. (When you visit this website in IE for the first
time, you will have to install a special ActiveX extension, and it’s better to add this website to the list of trusted websites.)
4.Using the search feature, find the KBs you need and click Add to add them to the basket. (It’s better not to select
more than 20-30 updates at once.)
5.Then click View basket to open it
6.Check Import directly into Windows Server Update Services (if this option is not available, make sure you have the
administrator privileges on your WSUS server) and click Import
7.Wait
till the updates are downloaded. (If the download suddenly terminates, try again.)
8.Then find the downloaded patches in the All Updates section of the WSUS console and confirm their installation to the necessary groups
of computers.
Using this method, you can import any updates from Microsoft Update Catalog to the WSUS server, hope it can give you a help.
Best Regards
Alan li
