The steps you followed to hide an update are correct. When you use BatchPatch to hide an update, the “Remote Agent Log” column will show the log of what was completed, and you can confirm that the update was hidden. Also, after you hide an update, if you then do a subsequent search for updates or download/install updates, the “Remote Agent Log” for that action will not include the hidden update, so you can confirm that too. This log is also saved to C:Program FilesBatchPatchBatchPatch.log on the target computer, so you can review it at any time. If you need assistance making sense of your log, feel free to email it to me for review. However, in your case it sounds like the update was hidden but was then later somehow re-released by Microsoft, or the update was never successfully hidden in the first place. I’m not sure, but it should be something that you can easily confirm by reviewing the logs.
