I haven't run it in Windows, but I run both the server and the client on a Linux laptop. The server is was actually does the scanning, and the client just manages the server. You can use OpenVAS-Client to manage a OpenVAS-Server, remotely or locally.
It doesn't look like OpenVAS-Server is supported on Windows (there is a Greenbone package available for the client only), so you will need a different place to run the server from, maybe a Linux VM would do the trick for you. You then have the option of running the client from the VM, or from Windows.
Hope that helps!
Put that in your pipe and grep it!
