TASK_LOGON_TYPE enumeration (taskschd.h)

Defines what logon technique is required to run a task.

Syntax

typedef enum _TASK_LOGON_TYPE {
  TASK_LOGON_NONE = 0,
  TASK_LOGON_PASSWORD = 1,
  TASK_LOGON_S4U = 2,
  TASK_LOGON_INTERACTIVE_TOKEN = 3,
  TASK_LOGON_GROUP = 4,
  TASK_LOGON_SERVICE_ACCOUNT = 5,
  TASK_LOGON_INTERACTIVE_TOKEN_OR_PASSWORD = 6
} TASK_LOGON_TYPE;

Constants

 
TASK_LOGON_NONE
Value: 0
The logon method is not specified. Used for non-NT credentials.
TASK_LOGON_PASSWORD
Value: 1
Use a password for logging on the user. The password must be supplied at registration time.
TASK_LOGON_S4U
Value: 2
The service will log the user on using Service For User (S4U), and the task will run in a non-interactive desktop. When an S4U logon is used, no password is stored by the system and there is no access to either the network or to encrypted files.
TASK_LOGON_INTERACTIVE_TOKEN
Value: 3
User must already be logged on. The task will be run only in an existing interactive session.
TASK_LOGON_GROUP
Value: 4
Group activation. The groupId field specifies the group.
TASK_LOGON_SERVICE_ACCOUNT
Value: 5
Indicates that a Local System, Local Service, or Network Service account is being used as a security context to run the task.
TASK_LOGON_INTERACTIVE_TOKEN_OR_PASSWORD
Value: 6
Not in use; currently identical to TASK_LOGON_PASSWORD.

Windows 10, version 1511, Windows 10, version 1507, Windows 8.1, Windows Server 2012 R2, Windows 8, Windows Server 2012, Windows Vista and Windows Server 2008:  First use the interactive token. If the user is not logged on (no interactive token is available), then the password is used. The password must be specified when a task is registered. This flag is not recommended for new tasks because it is less reliable than TASK_LOGON_PASSWORD.
