Installing Defender Definition Updates via WSUS

Question

Hi,
I have approved and downloaded definition updates for all computers.
I have a problem with installing all these definitions.
For example, in WSUS a server need 4 Definition Updates but only one update has been downloaded and I can install only that update.
If I install this update on the server and search for next updates, the server can't see any other definitions.

I have created an automatic approval rule with Defenition Updates.

Other updates have been downloaded and ready to download. Only Definition Updates are not downloadable.

I have checked if definition updates are not downloaded on the WSUS server. But the server the server has downloaded all updates.
Is it possible to download all needed definitions and install them all ?

Thanks for your posting on Q&A.

Would you mind sharing the Version of Security Intelligence Update for Microsoft Defender Antivirus - KB2667602 update installed on the devices first?

As far as I know, only the indeed Needed updates will be approved and downloaded after you enabled the automatic approval rule. If all the things going well, it seems that the other Security Intelligence Update for Microsoft Defender Antivirus updates aren't needed. Of course, we could try to approve the updates manually and check the windowsupdate.log on the client devices to check the information.

We could open PowerShell as an administrator and run the get-windowsupdatelog to get the log file. Note that the log file will be placed into the Desktop by default.

Thanks for your time and have a great day.

Best regards,
Rita

Thank you for your answer.
That's what I was thinking that these not downloaded updates aren't needed.
In view of Definition Updates I saw that these updates have been superseded by downloaded updates.
