unbound by default only provides recursive service to localhost (i'm not
sure what the BIND default is).  on debian and debian-derived systems
it's as simple as:

    apt-get install unbound && echo nameserver 127.0.0.1 > /etc/resolv.conf

there's an unbound_setup_1.4.0.exe listed right below the source tarball
on the unbound download page, so presumably the windows method involves
whatever the point&click equivalent of "echo nameserver 127.0.0.1 >
/etc/resolv.conf" is; perhaps this could be automated by the installer
with a checkbox.

the main problem with encouraging people to run their own recursive DNS
occurs when mobile users visit a network that intercepts or blocks port
53.  afaik there isn't an easy point&click way to toggle between the
locally installed recursive nameserver and the nameservers provided via
DHCP, nor is there a good way to detect and alert the user that port 53
mangling is occurring.
