1	Understand the problem scope.	Verify the following: Product the missing patch is associated with. For example, Windows 2012, .NET, Adobe, and so on. Patch release date Whether the patch is missing from a specific patch catalog or all patch catalogs
2	Identify the recent changes.	Verify whether the patch was previously present in a patch catalog. If yes, check whether any changes were made to the filters defined for the patch catalog. Also, check whether the patch is still available for download directly from the vendor.	Search for the patch on the vendor website and verify whether its available for download. For example - KB4534251 The following excerpt from the catalog update page confirms that this is a valid patch available for download :
3	Identify the associated product.	Do the following: Identify the product the missing patch is associated with, such as Windows 2012, .NET, Adobe, and so on. Verify whether the product is listed as an available filter in the CUJ.

Resolutions for common issues

Symptom	Action	Reference
The product (example, Windows 2012, .NET, or Adobe) associated with the missing patch is not listed as an available filter in the CUJ. All patches associated with this product are therefore missing.	Update the Windows Filter Configuration file to include the product associated with the missing patches.	Windows patch catalog
The missing patch was released very recently.	Do the following: Verify whether the CUJ was run after the missing patch was released. If the CUJ was not run after the patch was released, rerun the CUJ and confirm that it runs successfully to completion and check the catalog for the missing patch. If the CUJ was run after the patch was released, check the logs. If the CUJ is failing with errors, see this topic.
Patch is missing from one catalog, but is present in another catalog.	Do the following: Compare the filters defined for both the catalogs. Determine the filter on the successful CUJ that is responsible for downloading the missing patch, and add the same filter to the problematic catalog. Rerun the problematic CUJ and confirm whether the patch is included in the catalog.
Patch was previously listed in a patch catalog, but is no longer appearing after the recent CUJ runs.	Do the following: Check whether any filters were removed from the catalog recently. If yes, review the filter changes and whether any of these filters were responsible for downloading this missing package. If yes, consider adding the filter back. Rerun the problematic CUJ and confirm the package is now included in the Catalog as expected. If filters have not been removed recently, confirm whether the patch is still available for download directly from the vendor.
