Microsoft kills future security updates for Windows 7 on modern hardware

On the April 2017 patch day Microsoft has released two security bulletins KB4015549 and KB4015546 that will block future security updates on Windows 7 in case a newer processor is detected that is part of the following CPU Families: Intel KabyLake, AMD Bristol Ridge and AMD Ryzen.
The block mechanism is enforced by the new Windows Update Agent Version 7.6.7601.23735 this also prevents manual update installs. There is a UI nag screen that reminds you of the not supported hardware, even when the system is working ok.

The error in the log file looks like this:

c98 Agent WARNING: WU client failed Searching for update with error 0x80240037
f24 AU >>## RESUMED ## AU: Search for updates [CallId = {692C634C-461A-46AC-82FD-16C025C65F22}]

f24 AU # WARNING: Search callback failed, result = 0x80240037
f24 AU # WARNING: Failed to find updates with error code 80240037

An Offline install will also not work:

444 Agent WARNING: Only detected non-exempt updates on device with unsupported processor.
