My version (the .zip) is also (minimally) preconfigured, you just need to remove the ban nick on * so you can connect ;p.

Vista users, the GUI controller app will have a few issues unless you run it as administrator at the moment - however, this is NOT recommended.
Please do not report bugs on any of this on the tracker, instead talk to us on IRC at irc.inspircd.org #inspircd.
A final note that this IS pretty early on in the windows development, so it may come with free bugs, in fact, there's some chance it won't work at all! ;p. Try it and see.
Thanks, and enjoy.
