The administrator account is also created in Windows 8 as windows 7 or any old windows OS, but it is not enabled by default in Windows 8 operating system. It is better not to use the administrator account in Windows 7. If you do not need it, you can ignore it. It is advisable to use the administrative account for trouble shooting only.
