![]() ![]() Idle wait: The amount of time that the Task Scheduler will wait for an idle state to occur after a task trigger is activated or after the task is started on demand.Idle wait and Idle duration have been deprecated. Be aware that the amount of time the computer is in the idle state is independent of the idle duration time that was described previously. Idle end: The time when the computer transitions out of the idle state.Idle start: The time when the computer enters the idle state.The following list describes the idle conditions. ![]() They're still present in the Task Scheduler user interface, and their interface methods may still return valid values, but they're no longer used. The Duration and WaitTimeout settings are deprecated. Be aware that the illustrations start when the task trigger is activated or when the task is started on demand (without requesting to ignore the existing task constraints). The following illustrations provide three possible timelines that show how these different idle conditions relate to each other. The task settings can be used to define how the Task Scheduler handles the task when the computer enters an idle state. If reading or writing XML, the idle trigger is specified by the IdleTrigger element of the Task Scheduler schema. Defining an idle triggerĪ task can be started when the computer enters an idle state by defining an idle trigger.Īn idle trigger will only trigger a task action if the computer enters an idle state after the start boundary of the trigger.Īn application can define an idle trigger by using the IIdleTrigger interface. To mark the end of the idle state, Task Scheduler revises the resource consumption once in 90 minutes. When detecting the idle state in Windows 8 Server, Task Scheduler does not take user presence or absence into account. In Windows 8, the CPU and IO thresholds are set to 80%. In practice, this means that Task Scheduler may declare the system as idle immediately after user absence is detected, if the other conditions have been met since the last verification time. When any of the events above happens, Task Scheduler tests the computer for idleness since the last verification time. Battery level changed (only when on batteries).Task Scheduler makes additional resource consumption checks for the following events: When the user is away, the verification time is shortened to 30 second intervals. The resource consumption verification time is shortened to 10 minute intervals when the user is present. By default, the user is considered absent after four minutes of no keyboard or mouse input. However, Task Scheduler relies on the operating system power subsystem to detect user presence. ![]() In Windows 8, Task Scheduler performs the same general user absence and resource consumption checks. In Windows 7, when the Task Scheduler detects that the computer is idle, the service waits only for user input to mark the end of the idle state. In Windows 7, Task Scheduler considers a processor as idle even when low priority threads (thread priority < normal) execute. This flag forces Task Schedule to not consider the system as being idle, regardless of user activity or resource consumption.) (An exception would be for any presentation type application that sets the ES_DISPLAY_REQUIRED flag. The computer is considered idle if all the processors and all the disks were idle for more than 90% of the last detection interval. The user is considered absent if there is no keyboard or mouse input during this period of time. Task Scheduler checks for an idle state using two criteria: user absence, and a lack of resource consumption. In Windows 7, the Task Scheduler verifies that the computer is in an idle state every 15 minutes. This includes defining an idle trigger or setting the idle conditions for when the task starts. A task can be handled in several ways when the computer enters an idle state. ![]()
