How to determine windows updates are installed through SCCM or by system?

Question

In our SCCM environment some servers are having issue so I need to check which windows updates are installed through SCCM and which updates are installed manually online.

Answer 1

Please review the logs, it will tell you the source of where it was updated from.

Answer 2

Hi, @Microsoft_User

Thank you for posting in Microsoft Q&A forum.

First, you may check the software updates in SCCM console to see if you deployed the updates through SCCM.

We can also check the service IDs in WindowsUpdate.log to see which update source is being scanned.

For example, if the serviceID is 3DA21691-E39D-4da6-8A4B-B43877BCB1B7, the update source is SCCM.

You may also check UpdateDeployment.log in client to see updates deployment process by SCCM.
