That itself depends on the Windows install I think, and whether or not the client app has set it, if required.
There's no way you can check that from webserver side, so the answer to your question is no, you can't force it.
I would imagine with Windows that IE is set by default on install in the namespace for "ftp://".
It's possible that a rogue client app could overwrite that.
