I'LL SAY IT AGAIN AS SOME ARE NOT LISTENING
KB4056254 and KB4023057 are **NOT** Security Patches
THEIR PURPOSE IS TO FORCE YOU TO UPGRADE TO THE LATEST VERSION OF WINDOWS. HAS NOTHING TO DO WITH SECURITY.
Microsoft is moving away from "Delta Updates" (cumulative updates) to "Express Updates" that use differential updates, depending on the build/file versions, to mitigate the problem of the cumulative updates getting bigger and bigger over time. There is a great article about this
Link Removed. Patching Windows Update components can be considered a security update if it facilitates the delivery of future updates that mitigate serious threats. These threats are not just published by Microsoft, but other major corporations and governmental institutions like US-CERT.
If your concern is forced obsolescence, by design, being built into Windows, that has been going on for years. They overdid it with nag screens to upgrade to Windows versions, people complained, and they released optional patches to prevent the upgrade. But ultimately, they do have a time table to phase out updates for earlier versions of Windows. In particular, they are phasing out security updates for prior versions of Windows 10 because these are older builds of the same operating system, which I would estimate, require a very careful and arduous process of maintaining security updates compatible with every single build.
I would suggest re-evaluating why you are so fearful of future updates, especially if they streamline the update process or do not directly have an impact on you financially. If the updates are being distributed for free, and increase the stability of the Windows kernel and its various components, I don't see a problem. I'd also advise against blocking updates for most users, as you are only opening up your machine to potential security risks in the future.
