I just wanted to post what I did to get Windows 10 TP to work as a guest on a Windows 7 host. Using 4.3.18 I installed the VM with no issues. After the install when I added the Guest Additions they would always fail. Carefully looking at the failure it is apparent that its something to do with it not being able to open the files in the repository. For the GA for video the GA install points to vboxvideo8.inf_amd64 22e...edf folder in the guest systems file repository in system32. Then to the file vboxvideow8.inf, Which is the file that the GA install can't open. Other than the calling file having capital letters and the actual file that is in the repository having all lower case I can't see why it doesn't open it during GA install. I updated the video driver and forced it to use the Virtualbox video driver Windows 8. That worked though by not installing through the GA's installer none of the other updates were done. I actually had read that the VMWare 6.0 worked for Windows 10 TP. So I tried that program and it did install even with its tools. (I did this on a Win 7 Laptop with a I7 Cpu) The tools do not recognize the touchpad as such and there is no scroll like virtualbox. So back to virtualbox.

My solution was to go here http://download.virtualbox.org/virtualbox/ and download 4.3.8_RC1/. http://download.virtualbox.org/virtualbox/4.3.8_RC1/. I know that may be weird but I was willing to try anything to get it to read the correct install file. When loading the GA iso into the settings I used that file to run on. Opened Windows 10 TP VM and clicked on the install Guest Additions CD. Opened it in the VM and ran the GA VboxWindowsAdditions-amd64 as administrator. Oddly when this opened to the installer it was in fact installing GA's 4.3.18! All files were installed..

Edit: It seems that the file 4.3.18 is dated 10-11-2014 while the one I used 4.3.8 RC1 is dated 2-21-2014

Hope this helps anyone trying to do this.

I tried this, and it didn't work. From what I read, you first try the 4.3.18's, then the 4.3.8's? Whatever, it ended up locking up the VM. The reboot then got stuck. I ended up having to use System Restore to get it to boot properly again.

Basically, still many problems when 3D is enabled, and VB driver fails and Windows falls back to it's default driver if 3D is disabled.

Douglas, did you try your "solution" another time after it appeared to work for you?
You don't need to repeat this text in new threads just because you were told more than once in other threads that technically this cannot work this way.

Yes I did the same on my i7 laptop and it also worked. Have GA's working fine on both my desktop and laptop.

This didn't work for me.

If I attach the 4.3.8 GA ISO and try and run, I get an error that it can't be installed on this version of Windows.

If I attach the 4.3.8 GA ISO, then select Insert GA CD, the 4.3.18 ISO is used and I get the same black screen issues as you would expect.
