problem with removing index.php

[eluser]Skuja[/eluser]
Hi, I am new to all of this mod_rewrite thing. So I have followed thiswiki tutorial and still am expieriencing problems with removing index.php from URI.
I have following test controller with following code:

Code:

<?php
class Test_controller extends Controller {
    function index()
    {
        echo 'Hello World!';
        $this->load->helper('url');
        echo anchor('test_controller/test','test');
    }

    function test()
    {
        echo 'Look at this!';
    }
}
?>

when I open http://localhost/test/ it successfuly loads test_controller because it is set as default, but when I click on anchor hyperlink, the webserver throws object not found error, also this error appears when i'm trying to access my page this way: http://localhost/test/test_controller/
When I try to open my page with 'index.php' included in URI like this:
http://localhost/test/index.php/test_controller/
it works just fine.
I am using latest xampp application on windows based system.
The .htaccess file is identical to the one like in the tutorial, mod_rewrite is also set to load in httpd.conf.
So i would like your help to solve my problem to remove index.php form URI.
