The faulting module is VBoxDD.dll which tries to import dsound.dll which is not available on Windows Server Core installations. Providing a dsound.dll from a full windows installation fails from hardening checks (dsound.dll is not signed). Changing sound driver to none or null has no effect." defect closed other VirtualBox 5.0.4 fixed all Windows
