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.

AMD’s Bristol Ridge AM4 platform OEM release

The AM4 desktop platform is a long awaited refresh to replace the current AM3+ and FM2+ platform with
new chipsets that have USB 3.1 Gen1/Gen2 support and the support for DDR4 memory. The AM4 socket platform is the target for the current Bristol Ridge Desktop APUs and the upcoming Zen based CPUs and APUs.
Bristol Ridge for Desktops is a refreshed Excavator Core that was first released in Carrizo Mobile. Changes are: improved performance, support for DDR4 memory and several extended power saving mechanism.

AM4 platform for OEMs
The AM4 platform is currently only available to OEMs, e.g. HPs EliteDesk 705 G3 Series which we will cover a little bit. There is no support for Windows 8 or Windows 7 because of Microsoft’s support policy.

Update January 2017:
HP added Windows 7 Enterprise to the list of supported OS. This is a change to the Windows 10 only support policy earlier, the product documentation and the customer advisory was not updated to reflect this change.
There is also a new model 1AA87AW available that ships with Windows 7 Pro preinstalled. This is really good news as till now no other new CPU line (Apollo lake, Kaby Lake) comes with Windows 7 support.

cTDP feature in latest AMD and Intel processors

Configurable TDP (cTDP) is a mechanism to change the standard TDP of a processor to a lower TDP that requires less power and cooling compared to the standard TDP. This is achieved by a lower core frequency and voltage. cTDP is a requirement if the cooling solution of the CPU is not suitable, e.g. very thin devices or when a quite mode is preferred over the maximum performance mode. AMD made this feature first available in selected models of the “Kaveri” based A-Series. Intel introduced this feature in the U/Y Series of ultra low power “Haswell” mobile and newer mobile “Broadwell” CPUs. The cTDP feature from Intel is controlled by the firmware/EC and is set by the device manufacturer and cannot be changed, AMDs implementation allows the user to set this feature on selected desktop models (Kaveri, Carizzo) when the required option is available in the firmware/BIOS.
Mobile CPUs e.g. AMDs 2016 35W “Bristol Ridge” models have a cTDP range of 25-45W and
Intels 2016 “Skylake” top U-Line models have a base TDP of 28W and a lower cTDP from 23W to 22.5W (low power mode). The device manufacturer can set the value that fits the cooling solution in that device. In this case the setting is locked by the manufacturer and cannot be changed. The advantage is only one CPU for different thermal envelopes, but you have to check what cTDP is set to compare speed and battery life of the same CPU model.
