This isn't what I see:

C:\Temp>type abu.rb
p ARGV

C:\Temp>abu what ever you want
["what", "ever", "you", "want"]

Now, in the registry, the default value for HKEY_CLASSES_ROOT\.rb is
"rbFile" and the default value for
HKEY_CLASSES_ROOT\rbFile\Shell\open\command is:
"c:\ruby\bin\ruby.exe" "%1" %*

I suspect that your registry entry is missing the %* bit. Go open up
regedit, find HKEY_CLASSES_ROOT\.rb, find that default value (probably
rbFile, but if it isn't use that value where I say "rbFile"), then
find the default on HKEY_CLASSES_ROOT\rbFile\Shell (probably "open"),
then look at the default on
HKEY_CLASSES_ROOT\rbFile\Shell\open\command and see if that includes
the %* bit. If it doesn't, add it.

IIRC, assoc command built in cmd.exe does it. Try assoc /?.

Sorry, it was ftype.

assoc .rb=rbFile
ftype rbFile=ruby "%1" %*
