Windows 10: Task Scheduler - trigger not working properly

Hi,


I've been trying to create a scheduled task using the "at log on" Any user type and this appears to only trigger if I log out and log back in the user once Windows has already loaded.


However, after a clean Windows restart/shutdown cycle, the event will not trigger at all - almost as if Task Scheduler itself is not actually running when the account is logged in after a clean system boot? Hybrid Shutdown & Fast Start are disabled on the device


Has anybody else encountered this and found a fix?


I'm testing with Windows 10 v1909.

Any help most welcome!

Task Scheduler: task gets triggered by event but does not start

I know a thing or two about the Task Scheduer but so far I am unable to wrap my mind around your problem. Here is why:

• I do not recognise the screen snapshot your posted. What is it?
• What event is supposed to trigger the scheduled task?
• What is the scheduled task supposed to run?
• You write "there is the initial event 108 showing the event getting triggered". How can an event trigger another event?
• Do time-triggered tasks work reliably?

 

App Runs Properly but Win10Pro Task Scheduler Cannot Run It

We have a requirement for extremely accurate computer clock time and use a small app that that, when launched, checks with a pool of time servers and syncs our computer clock. We want to schedule this app to run every couple of hours.

The app runs properly when I launch it manually. I created a task in Task Scheduler to do this automatically every two hours and, when I manually run the task within Task Scheduler, it also runs properly. However, it will not run on on its own on a schedule.
Task Scheduler fails to launch it.

On a different computer, another app is able to launch it when that app is launched but, again, Task Scheduler fails to launch it on a schedule.

The task is configured in Task Scheduler as follows:

GENERAL

• When running the task, use the following user account: it's my own account, and I am an Administrator on the computer
• Run only when user is logged on
• Run with highest privileges
• Configure for Windows 10

TRIGGERS

• Trigger: At task creation/modification
• Repeat every 2 hours for a duration of indefinitely
• Enabled

ACTIONS

• Start a program "path...\SysTimeUpdate.exe" min ('min' being an argument)

CONDITIONS

• none - no conditions

SETTINGS

• Allow task to be run on demand
• Run task as soon as possible after a schedules start is missed
• Stop the task if it runs longer than 1 hour
• If the running task does not end when requested, force it to stop
• If the task is already running, then the following rule applies - Stop the existing instance

Someone suggested that my Administrator account may not have full privileges, and it may be a permissions issue but, if so, why can I launch it manually and why can another app launch it when that app is launched but Task Scheduler cannot? This very very
baffling, and any assistance would be very much appreciated. Thank you.

 

Windows Task Scheduler does not trigger a task, after a PC-restart during the day

Hi Jarius,



Thank you for your reply.

• On October 25, 2016, I checked the Windows Task Scheduler settings, according to your advice.
• The next morning I powered-on my PC at 09:30 and made a screendump of the Task Scheduler at 10:08.
  
  At that time 2 of my 5 scheduled backup task were triggered conform schedule and the according backups were carried out correctly (see the green framed surfaces in the 10:08 window below)
• I powered-off my PC at 10:12 and powered it on again at 15:45.

• At 15:50 I made a sreendump of the Task Scheduler window, where was indicated that 3 backup tasks were carried out correctly in the past at about 10:00 (see the green framed surfaces in the 15:50 window in the picture above).
• At 16:40 I made a screendump again. Now the backup task that were triggered after the first power-on at about 10:00, now were not triggered anymore (the red framed surfaces in the 16:40 window) and the backup task that were not triggered during the first
  power-on, were now triggered correctly at about 16:00 (the green framed surfaces in the 16:40 window).
• I also made screendumps again at 17:40 and 18:40. In both cases the backup tasks triggered during the first power-on at 9:30 were not triggered anymore and the backup tasks that were not triggered during the first power-on were correctly triggered with
  the scheduled 1 hour interval.

My conclusion:

• If my PC is powered-on before the first scheduled backup task, all backup job triggers are carried out conform schedule.
• After a PC restart the previously triggered backup task are not triggered anymore during the rest of the day.
• Only backup tasks that were not triggered before the PC restart, are triggered correctly after the PC restart.
• A manual run of a backup task always result in a correct backup task trigger.

This must be a bug in the Windows Task Scheduler.



I hope you will find a solution for this problem.



Best regards, Wim
