[Solved] Windows 10 (build 9926) seems to break the GAs.

NOT solved: I installed 4.3.21-97986, but I when I choose Devices/Shared I still get "The Virtualbox Guest additions do not appear to be available .... When I try to start from Services, I get error 1053: the service did not respond.

They work for me. Attach the vbox.log (compressed) for your W10 guest.

VBoxGuestAdditions_4.3.21-97986.iso Seem to work in Windows 10 Build 9926.

I too had trouble with the display adapter and one other Vbox driver but since installing this GA iso it seems to have fixed it. Thanks

I installed VBoxGuestAdditions_4.3.21-97986.iso and the only issue that I have now is the display driver.

Windows 10 Pro Technical Preview Build 9926 64bit running on a Windows 8.1 64bit host using VirtualBox v4.3.20 r96997.

VirtualBox Graphics Adapter for Windows 8 - Windows has stopped ths device because it has reported problems (Code 43)

Everything else seems to be working now.

Driver Provider: Oracle Corporation
Driver Date: 1/30/2015
Driver Version: 4.3.21.0
Digital Signer: Oracle Corporation

Any suggestions? Thanks!

Ok so I fixed my problem!

1.) After you install the test version on the VirtualBox Additions, shut down your virtual machine that is running windows 10 technical preview.
2.) Go to settings for this virtual machine and go to Display.
3.) Check the box for Enable 3D Acceleration.
4.) Set Video Memory to 128MB (if it isn't already)
5.) Click Ok

That should fix it.

I also checked the box for Enable 2D Acceleration but it may not be necessary.
