If you’re trying to apply this month’s patches — an exercise in futility that I continue to discourage — you may have found that this month’s patches and their documentation read like a da Vinci script, mirrored upside down and backwards.
Take this astounding bit of bafflegab, from the official Microsoft Exchange blog:
For operating systems prior to Windows 2016, the update will be applied as an additional update to the updates released on July 10th. This means you must apply the July 10th update and then may need to execute Windows Update again to receive the additional update to fully resolve the issue. ...
According to the Windows Servicing team, for the non Windows Server 2016 operating systems, it is required that the update released on July 10th be installed for Windows update to offer the new update. [This] is because the update is a patch to the previous package. Windows update chooses updates based upon packages previously installed on these operating systems.
