Well you have to name the account when you set it up. Windows does not by default create an account called 'AdminProAccount'. It will by default create the Administrator account during the OS install if you choose to enable it.
I am going to go out on a Limb here and tell you how to wipe out an admin password, but it requires access to an admin account. So, if you don't have admin access to begin with, this method is useless to you. This is not a hack, but a built in feature that allows any user with admin rights to a machine to change the password locally.
Right click on My Computer, select management, click on local users and groups, click on the Users folder, right click the admin account, and choose the clear password option. Remember, if you don't already have admin access this will not work.
