jIRCii
jIRCii is a barely graphical standalone Java client, with a look and feel inspired by ircII but taking advantage of modern GUI functionality.
Web Based Clients
Webchat interfaces are listed elsewhere, and are available anywhere there’s a working web browser.
Linux/Unix Clients on Windows
Many of the terminal-based Unix/Linux IRC clients have been ported to run on Windows with the aid of WSL, Cygwin or MSYS. These ported clients may be awkward to use if not comfortable with console-mode applications, and primarily cater to advanced users.
- irssi
The popular X11 client, xchat, also has a Windows version, which is a common alternative to mIRC on Windows systems.

mIRC is known to work well with Wine.
