After Updating to Windows 10 Enterprise Insider Build 15002 VirtualBox 5.1.12 Won't Launch, below is the error I am receiving. I uninstalled and reinstalled Virtual Box, as well as tried starting in Win 8 Compatibility mode. Let me know if you need any other info.

Preview/Inside/Test build problems are usually not a bug, since 1) they're testing playground and 2) a bug is something that is documented as a working feature, but fails.

For discussions of that nature, there are dedicated forums. For example your problem has already been reported two days ago. See: ​VirtualBox on Windows pre-releases and more specifically, ​Windows 10 Build 15002+ - VirtualBox fails to start.

Hopefully fixed in the most recent test build. Please confirm.

Virtual Box can open now, but still cannot start a vm successfully, log file is attached, please analyses it.
