Enable mbstring extension on Windows

I just downloaded a fresh copy of Drupal 6.12 and ran it on my local machine for the installation procedures!
It was okay until I saw a notice message telling me that mbstring is not enabled on my php installation.
Now I am running across a situation, I can't get mbstring working on windows.
On linux it's very simple, in fact I already got it installed by default.
I don't like to have a resource and not being able to use it for whatever reason it is.
Specially, I think that in the case of mbstring, which is not default to php,
the guys of Drupal should provide a help on such subject for the best use of the CMS.

Below is my excerpt from php.ini file which contains the configuration of mbstring:
(Just to note I have uncommeted php_mbstring;)

[mbstring]
mbstring.language = all
mbstring.internal_encoding = UTF-8
mbstring.http_input = auto
mbstring.http_output = UTF-8
mbstring.encoding_translation = On
mbstring.detect_order = UTF-8
mbstring.substitute_character = none;
mbstring.func_overload = 0
mbstring.strict_encoding = Off
