What 'wait for idle for' as 'do not wait' means?

There is already a question asking Task scheduler - What is "Wait for idle for"?, but I could not understand what the Do not wait thing does when Start the task only if the computer is idle for is set to something as 10 minutes.

I have set the trigger action as On idle, When the computer is idle.

What will happen when the Wait for idle for is set to Do not wait and Start the task only if the computer is idle for is set to something as 10 minutes? Will the task never start because I set Do not wait? What Do not wait mean? Do not wait what?

Solution 1:

The iddle settings in "Conditions" work with any kind of trigger, not just on iddle.

When the trigger fires:
Task Scheduler (TS) checks if the computer has been, up to this moment, in an iddle state for 10 min (per your setting).

• If yes, then it will run the task - regardless of what is inside the "Wait for idle for" box.
• If no, then it will wait for the condition "computer has been in iddle state for 10 min" to become true - and will wait for up to an amount set in the... "Wait for idle for " box. If in that box is Do not wait then... it will not wait at all! but instead will call it quits and not run the task for this instance/firing of trigger.
  It will try to run it next time the trigger will fire.
  If that trigger happens to be set "On iddle", then the new firing can happen no sooner than 15min later, because TS only checks whether computer is in idle state every 15 min.

Now goto "When the trigger fires:".
