What is the Difference Between Windows Administrator and Windows Users
Is there a difference in privileges between the Windows administrator user and the system user?
There have been several times when I need to promote the cmd window to system privilege to delete some files. This may be because the files are locked by the system user, or the system user may have higher access. I hope to find out if there is a difference in privileges.

from Microsoft KB :
The system account and the administrator account (Administrators group) have the same file rights, but they have different functions. The system account is used by the operating system and services that run under Windows. There are many services and processes in Windows that need to be able to log on (for example, during Windows setup). The system account was designed for this purpose; it is an internal account, not visible in the User Manager, cannot be added to any groups, and cannot have user rights assigned to it. On the other hand, the system account appears on the NTFS volume in File Manager under Permissions under the Security menu. By default, the system account takes full control over all files on the NTFS volume.Here, the system account has the same functional privileges as the administrator account.
