Returns all instances of the currently running registered task.
Note IRegisteredTask::GetInstances will only return instances of the currently running registered task that are running at or below a user's security context. For example, for members of the Administrators group, GetInstances will return all instances of the currently running registered task, but for members of the Users group, GetInstances will only return instances of the currently running registered task that are running under the Users group security context.

LONG flags,
[out] IRunningTaskCollection **ppRunningTasks
