For future reference, please provide complete information about your host, your guest and your VirtualBox. Use the complete version numbers (including the build numbers) to identify your software:
"OSX" isn't enough, "OSX 10.9.5 build 13f1911" is much better.
"Win10" isn't enough, "Win10 1607, build 14393.969" is much better.
"Ubuntu" isn't enough, "Ubuntu 16.04, 4.4.0-59-generic #80-Ubuntu SMP" is much better.
"The latest VirtualBox" isn't enough, "VirtualBox 5.1.22 r115126" is much better.

When do you get the critical error? At launch? At runtime?

Ah, OK... We're talking about a BSOD in Windows then. That may not be necessarily a VirtualBox problem. Just because an OS/program that runs in the context of VirtualBox has a problem, it doesn't make it a VirtualBox problem. You're having an issue that has most probably nothing to do with VirtualBox, so my suggestion would be to treat it as such, as a native problem with the OS or the application of the guest.
