I just finished updating our staging sharepoint server to the january CU. I also installed all the server and security updates through microsoft udpates. I noticed that when I finished my build was 4797 instead of 4787.

Do I have to forgo security updates to stay on a certain build number? I was under the assumption that only the sharepoint updates from the download center would update the build number.

No, not all SharePoint patches will change the build number. There are two factors:

  1. If the schema is updated and/or if Microsoft.SharePoint.dll is updated.

  2. The build number on the KB has a higher build number than the Microsoft.SharePoint.dll.

These will cause the build number to not increment to the expected version and is perfectly normal.

    So I should be weary of even security updates for SharePoint? I use the build number to indicate what CU I am on. So if I want to stay on a certain build I should avoid all updates beyond that release date? I see so many best practice tips to avoid any SharePoint update that doesn't affect your farm. Security updates, I believe, meet that criteria.

    Always be weary of any SharePoint patch. They need testing. That said, the best way to determine installed patches is through Central Admin -> Upgrade and Migration -> Check Patch Status.
