STATUS_INVALID_TASK_NAME

The task identifier is outside the accepted naming contract

STATUS_INVALID_TASK_NAME identifies a specific Windows status in the job, task, callback, or isolation path. The task framework rejected the supplied name before joining or scheduling the task. The restriction may include namespace, encoding, length, or reserved-name rules.

Record the exact name and API, compare it with names already registered, and avoid normalizing or truncating identifiers silently.

What to preserve before changing the system

  • The exact API, caller, target object, original NTSTATUS value, and any nested error or activity ID.
  • For STATUS_INVALID_TASK_NAME, the relevant process token, package/job/enclave identity, lifecycle state, and policy or mitigation settings.
  • For STATUS_INVALID_TASK_NAME, operational event logs and a timeline showing the first transition into the failing state.
