I can't reproduce it on my Win8.1 VM, Win10 VM and Win10 physical host. I used VMware Workstation 11.1.2 for my VMs. I don't know which type your VM is? There shouldn't be pretty much hardware difference between VMs. What special software has you installed on your VM? The boldest idea is that you provide a VM image that occurs this problem if you like.

In the VM system settings, I have checked IO-APIC, PAE/NX, VT-x/AMD-V and nested paging options with 2 processors. The network adapter is using the default setting (NAT).

I just gave a try to Npcap 0.04 on a Windows 10 x64 host and everything is working fine (no BSoD, loop back interface present and capturing data). So it could be a bug on VirtualBox side (I just saw that they released version 5.0.2 and claim that Windows 10 is not officially supported yet due to issues remaining) .
The ultimate test will be on the Windows 7 PC that was crashing before but I cannot give it a try before the 1st of September.
BTW Npcap 0.04 still reports version 0.03 in the version string retrieved by Wireshark.

With DebugView on ("Capture Kernel" on and "Enable Verbose Kernel Output" on), then install this debug version Npcap, launch Wireshark. The error message should then be recorded in DebugView, save the text into the log file and give it to me. Through this way I could know the failed function call and its error code, while I don't know if this could give me enough information to fix it, but it's an easier way.
