Ran the installer
cwRsync_2.0.10_Installer.zip

Then found the example batch file, modified it by adding one line at the end:
rsync rsync://wiki.tcl.tk/wiki/wikit.tkd .

And then just ran the batch file
wikit-rsync.cmd
I renamed it with a .txt extension as well so it's not run by mistake.

Enjoy y'all smart people using Windows!
