We were checking that latest release of patches were being deployed, and found an Issue with at least a couple.

Many of our Windows 11 were not receiving a couple patches.

Cumulative Update Win11 .Net  (KB5039895)

Cumulative Update Win11 23H2 (KB5040442)

Scanning the system did not show these as required in Missing Vulnerabilities.
They were not in the Installed either.  

They did appear in our Defender Endpoint portal as missing patches.

When we ran a manual Windows Update - they were installed through this process.

We have deployed both these patches to all Win11 systems via Configurations.  

But now I wonder what other patches are missing or not being associated to which systems.
