problem with guid, when i change the folder name

Question

I'm new to WordPress. I started the site as good with folder name wordpress. After I changed the folder name from wordpress to test. And also change the siteurl from http://localhost/wordpress to http://localhost/test in wp_options table. And I modified the guid with this refer.

My problem is, still I click any 'post' or 'comment', that goes to http://localhost/wordpress/?p=7#respond page only. I want that's goes to http://localhost/test/?p=7#respond.

Anyone can?
