Windows 10: Windows HLK "DXGI Gamma Ramps" test crashes

Hello everyone.I have a problem running "DXGI Gamma Ramps" test with Windows HLK Studio. When I run it, DXGIGammaVM.exe, which contains tests, crashes with Access Violation 0xc0000005. I can also see the following error in HLK log just before crash log:clsDXGISwapChain::InitBBViaClear: Clear failed with error 0x0.However, the WoW64 version of this test "DXGI Gamma Ramps WoW64" completes successfully, and there is no InitBBViaClear error line for it, too. Also, the same issue can be reproduced with "VirtualBox Graphics Adapter WDDM" driver, which is installed with Guest Additions teste

Windows HLK - Router Testing on Windows 10

I planned to perform Wireless Router Testing for Windows 10 using the HLK toolkit.

As per the basic HLK requirement, I brought up the HLK Controller by installing the Controller + Studio in a Windows 2008 Server and have installed Clients from the Controller's share in 4 Windows 10 PCs

As per this link, https://msdn.microsoft.com/en-us/library/windows/hardware/dn974571(v=vs.85).aspx,
there should be configuration jobs and test jobs available for configuring and performing the “Router” Tests. But no jobs or Features were seen on the HLK manager under $\WDK Tests\Networking.

Later I installed WDK for Windows 10 in the Controller (Windows 2008 Server) hoping to find some jobs/Features being populated under $\WDK Tests\Networking, but still no jobs or Features were listed.

Being a beginner, I couldn’t assess if any additional package is missing or any configuration change or “Job/Feature imports” to be performed in HLK. Moreover couldn’t find any reference for it in the Documentation too.
