SCCM vs Windows Update
I am new to SCCM as I have recently been allowed in my new position to begin to understand it and it's complexities. However, a discussion came up during a Manual patching deployment for a few machines that confused me.
Scenario - SCCM reported that only two patches were needed for specific machines that are requiring manual patching due to an undetermined network connection issue. The systems (Windows Server 2016) haven't been patched in several months nor rebooted to get a GPO (another story). The systems were updated with the patches that were recommended which had several rollup patches however, Windows Update shows errors on old patches and showing the system not up to date.
Question - Is there a difference on how SCCM determines the patches needed for a system and the way Windows Update would determine the patches needed? The statement that brings this question is "Windows Update can't scan systems". That to me would suggest that Windows Update doesn't do an evaluation of the system requirements after querying the catalog for updates to determine which have already been installed and which need to be installed.
Not that I want to use Windows Update and a manual process I am just trying to understand the difference here that would suggest that statement to be made.
