SCHED_E_TASK_ATTEMPTED
SCHED_E_TASK_ATTEMPTED means Task Scheduler tried to start the task, but a constraint in the task definition prevented it from running. It is more specific than a missing executable or generic service failure: the scheduler reached the task and then applied one of its configured conditions.
Check constraints as a set
- Review whether the task is enabled and whether its triggers are active within their start and end boundaries.
- Inspect conditions and settings such as idle requirements, network availability, battery restrictions, session conditions, execution limits, and multiple-instance policy.
- Read Task Scheduler history around the attempted start to find which configured condition stopped the launch.
Make the intended policy explicit
Change only the condition that conflicts with the task’s required behavior. Removing every constraint can make a maintenance task run at an unsafe time, on battery power, or without the required network and user context.
