Windows Patching Job reports an old patch missing, even though the patch is shown as Obsolete in the Catalog, and there was no Include Filter used during the analysis run.
The Bulletin in question is most likely Partially Superseded, where the patch that's returned during the Patching Job is not actually obsolete. The following needs to be validated for the hotfix in question:
As an example, I will use KB977290 hotfix from old superseded bulletin MS10-014:
MS10-014 [Superseded By MS11-013]:
As you see, the newer MS11-013 Bulletin does not have the hotfix for Windows 2000, so the corresponding patch from older MS10-014 Bulletin is still considered new.
If you run analysis against Windows 2000 server, expect to see hotfix KB977290 in the results.
