Hi guys, I am new here.

I use Vbox 6.0.8 source code to build windows wddm graphic driver only.I USE VBOX_ONLY_ADDITIONS=1 option. But I do not build additions iso.
After install VBoxWddm.sys, VBoxVideo.sys and many dlls(include UMD dll and OGL dll) to win10. The 3D function works very well. But video player which use VBoxDispD3D.dll, VBoxNine.dll and VBoxSVGA.dll normally crash everytime when I play video.
I wonder if I have lost some Windows registry Key/Value,or Other configuration options.

Thanks!

First, mandatory question; why? ;)

Second, I would start going through the GAs installer files: https://www.virtualbox.org/browser/vbox/trunk/src/VBox/Additions/WINNT/Installer

Third, I would try with the official method and the built-in GAs ISO. Does the app crash when you do it the "official way"?
