From the developer:
The Irssi for Windows installer and portable packages are finally in the process of being updated for Irssi. Before the new Windows binaries are released, we'd like some Windows users to test the installer in order to prepare it for prime time. If you would like to help with the test effort, please read the testing notes that outline the testing details, then download the test installer.
You may want to check out more software, such as iisadmin, sforce Explorer or Novell Privileged User Manager, which might be similar to Irssi.
