Windows 7 / Getting Started

Securing Running Tasks

Task Scheduler supports an isolation model in which each set of tasks running in specific security contexts are started in separate Desktops. The execution defined and started by the trigger is handled by engines running in transient processes in a user or computer context. Tasks can be started in a system account context, such as LocalSystem, LocalService, or NetworkService, or in a specified user account context. Tasks started in a system account context will always run noninteractively in Session 0.

The CreateProcess function used to create tasks ensures that any Winstation created in a user context will run in a different session than Session 0. By default, all Winstations will be created in the same session.

Registration Permissions Matrix

The Task Scheduler service adheres to the following task registration permissions rules:

  • Any user can schedule any task for herself.
  • Any user can schedule any task for anyone whose password she supplies at registration.
  • An administrator or system account can schedule tasks for other users or security groups without supplying a password, with the following restrictions:
    • Only with the Run Only If Logged On flag set, which is similar to a logon script and consistent with current behavior
    • Only running in interactive mode
  • Tasks scheduled with RunOnlyIfUserLoggedon with no password will run only in interactive mode.
  • Tasks scheduled to run in system contexts such as LocalSystem, LocalService, or NetworkService will not run in interactive mode.
