Win32_SystemAccount Class

The Win32_SystemAccount class represents a system account. The system account is used by the operating system and by services that run under Windows NT. There are many services and processes within NT that need the capability to logon internally (for example during a Windows NT installation). The system account was designed for that purpose; it is an internal account, does not show up in User Manager, cannot be added to any groups, and cannot have user rights assigned to it. On the other hand, the system account does show up on an NTFS volume in File Manager in the Permissions portion of the Security menu. By default, the system account is granted full control to all files on an NTFS volume. Here the system account has the same functional privileges as the administrator account.
Namespace value is root/CIMV2.
WMI Provider value is CIMWin32.


  • Caption
  • The Caption property is a short textual description (one-line string) of the object.

  • Description
  • The Description property provides a textual description of the object.

  • Domain
  • The Domain property indicates the name of the Windows domain to which the system account belongs.
    Example: NA-SALES

  • InstallDate
  • The InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.

  • LocalAccount
  • The LocalAccount property indicates whether the account is defined on the local machine. To retrieve only accounts defined on the local machine state a query that includes the condition 'LocalAccount=TRUE'.

  • Name
  • The Name property indicates the name of the Win32 system account on the domain specified by the Domain member of this class.

  • SID
  • The SID property contains the security identifier (SID) for this account. a SID is a string value of variable length used to identify a trustee. Each account has a unique SID issued by an authority (such as a Windows domain), stored in a security database. When a user logs on, the system retrieves the user's SID from the database and places it in the user's access token. The system uses the SID in the user's access token to identify the user in all subsequent interactions with Windows security. When a SID has been used as the unique identifier for a user or group, it cannot be used again to identify another user or group.

  • SIDType
  • The SIDType property contains enumerated values that specify the type of security identifier (SID). SIDTypes include:
    SidTypeUser - Indicates a user SID.
    SidTypeGroup - Indicates a group SID.
    SidTypeDomain - Indicates a domain SID.
    SidTypeAlias - Indicates an alias SID.
    SidTypeWellKnownGroup - Indicates a SID for a well-known group.
    SidTypeDeletedAccount - Indicates a SID for a deleted account.
    SidTypeInvalid - Indicates an invalid SID.
    SidTypeUnknown - Indicates an unknown SID type.
    SidTypeComputer - Indicates a SID for a computer.

  • Status
  • The Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.
