Hope this clears things up a bit.
Power Users:
Members of this group have all the access permissions that Users and Power Users had in Windows NT 4.0. Power Users have read/write permission to other parts of the system in addition to their own profile folders. Power Users can install applications and perform many administrative tasks. If you are running applications that have not been certified for use with Windows 2000, users will need to have Power User privileges.
Administrators:
Members of this group have total control of the desktop, allowing them to complete all tasks. Members of the Administrators group have the same level of rights and permissions they did for Windows NT 4.0. There is also a built-in administrator account that allows administration of the computer. The administrator account is the first account that is created when Windows 2000 is installed.
