I can't reproduce that crash on 2008R2 (server version of Windows 7),
but the server I just tried it on might be a version or two behind. What
version of GPLPV are you using?

For an 'empty' cdrom, the PV driver backend doesn't like having no path.
In this case I just create an empty iso (mkisofs on an empty directory)
and use that. That said, it shouldn't cause Windows to crash but you
will see a failed device.
