A Microsoft Windows NT and Windows 2000 system group existing on all Windows NT and Windows 2000 servers and workstations that is used as a security context for running services and operating system functions.
The membership of the Creator Owner system group cannot be modified directly.
The Creator Owner system group includes only the user who created or took ownership of a network resource, and is functionally equivalent to that user’s primary group.
The Creator Owner system group has full permissions on the resource, but the rights of the Creator Owner system group cannot be modified. Whoever creates a file system object or print job becomes the Creator Owner of that object or job.
