after wordpress was installed by my IP,
And that’s why you don’t use one click installers or let your host install WP for you. ??
You can change the name of that user via phpMyAdmin — look in the wp_users table and change it to what you like. However, it’s probably better to login with that ID, create a NEW admin user the way you want it, then logout, login as the new user, and then delete the original user. When you delete that user, it will ask you what to do with content owned by that user. Transfer it to your new ID.
