Failed to create Direct3D 12 device

Error 887A0004: Die angegebene Geräteschnittstelle oder Featureebene wird auf dem System nicht unterstützt.

On a HD 530 (i7-6700k) DX12 support disappeared when running HD 530 as primary device. This is tested on Windows 10 x64. Is this a nasty bug or intended? This didn't happen in older 15.40 drivers. Because when running as secondary device it detects DX12 support as you can see below. Why doesn't Intel support DX12 with this driver when running as primary device? This driver is also hosted on Microsoft update page declared as WHQL driver!

The latest graphics driver right now is version 4279

Driver 4300 seems to be Microsoft Inbox version.

Are you getting DirectX 12 support with driver version 4279?

This driver is hosted on a Intel page as well. And is doesn't matter what OEM or manufacturer this driver is hosted on, this is a driver from Intel, a production driver to be exact. Intel released this driver, otherwise Microsoft couldn't host it. As I said all previous 15.40 drivers were correctly working with DX12 support. So is it bug from Intels side or is the removal of DX12 support an intended move?

[Allan_J_Intel1]

Yups, I see the driver version 4300 was released for Intel(R) NUC only, do you have an Intel(R) NUC? You mentioned i7-6700k and the latest driver for your HD 530 graphics is https://downloadcenter.intel.com/product/88345 Downloads for Intel® HD Graphics 530 for 6th Generation Intel® Core™ Processors

You clearly don't understand the problem.

if the driver is for nuc only why does windows update say it is the latest driver

lastley nowhere on the driver during the installing does it does it say it is for nuc only

[Allan_J_Intel1]

The driver /message/341009# 341009 15.40.4.4300, has not been officially released on the graphics area. I do not have information about the release notes until the driver is available on the Graphics download section.
