I added windows 7 but had to delete windows 98 from the xml to make it work. To do it go into Plugins->Manage Plugins->Display OS and Browser->save on new post

Repalce ALL with:

$vbulletin->db->query_write("INSERT INTO " . TABLE_PREFIX . "postinfo (postid, OS, browser) VALUES (" . $post['postid'] . ",'$os' ,'$browser')");

Then edit Display the information on postbit:
