You can either add the --noreadline parameter to the ruby calls at the
top of irb.bat like so:

@echo off
if not "%~f0" == "~f0" goto WinNT
ruby -Sx "%0" --noreadline %1 %2 %3 %4 %5 %6 %7 %8 %9
goto endofruby
:WinNT
"%~d0%~p0ruby" -x "%~f0" --noreadline %*
goto endofruby
...

or you can insert it into ARGV in the Ruby section:

...
require "irb"
ARGV.unshift "--noreadline"
...

My favourite feature of disabling readline is that you can right-click
on the console window to access the Mark, Copy and Paste operations.

Cheers,
