At least not for me, my Windows box didn't get an IP if I enabled the Prefix for the internal interface, I had to leave that at off and manually do a DHCPv6 server.
Just click the 'other config' checkbox, this enables DHCPv6 as well using the values configured at Prefix Advertisements. That will get your Windows Clients to retrieve the DNS Server settings as well.
