Is It Possible to Change Default Windows Idle Time for Task Scheduler?
- by alharaka
From the official Microsoft docs:
  Detecting the Idle State
  
  The Task Scheduler service will verify that the computer is in an idle
  state every 15 minutes.
  
  The computer is considered idle if all the processors and all the
  disks were idle for more than 90% of the past 15 minutes and if there
  is no keyboard or mouse input during this period of time. Besides, any
  presentation type application that sets the ES_DISPLAY_REQUIRED flag
  will make Task Scheduler to not consider the system as being idle.
  
  In Windows 7, Task Scheduler considers a processor as idle even when
  low priority threads (thread priority < normal) execute.
Is there any way to change the time to less than 15 minutes minutes?  Am I assuming this hard-coded and impossible?  My Google-fu has eluded me so far and I found nothing, but wanted to check here before giving up.
