Windows 10: Oddly named tasks in Task Scheduler revealed

The following relates to oddly named tasks of of the form {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxx}, where "x" is a seemingly random hex digit, which are shown in the "Task Scheduler" Microsoft application in Windows 10.


The following image along with the text below it show how to display these tasks. Click this image to display an enlarged version in a new window.








The Task Scheduler shows and allows control of scheduled background tasks. This can be invoked by entering "Task Scheduler" in the Microsoft Cortana Search Box and pressing the Enter key.


This application allows logging of the scheduled background tasks. To enable this click on the "Enable All Tasks History" option in the "Actions" pane on the right side of the display.


Wait at least 12 hours and then click on the "Task SchedulerLocal" item in the left hand pane. Then in the dropdown "Task Status" pane in the middle of the display select a time period of "Last 24 hours" or more.


Scroll down to the end of the list and you will see one or more oddly named tasks of the form {xxxxxxxx-xxxx-xxxx-xxxx-xxxxxx}, where "x" is a seemingly random hex digit.


Note these tasks are not shown in the "Active Tasks" pane nor revealed by the "Display All Running Tasks" menu item in the right hand pane.


What are these tasks?

Oddly named tasks in Task Scheduler?

Hi,

I've recently enabled the 'Task History' option on Task Manager, and this has led me to find some strange-looking tasks that seem to happen every day, roughly around 9 hours after I've turned my computer on. These tasks don't appear on the "Active Tasks" tab, nor anywhere else on the Task Scheduler (not even on the "Running Tasks" window while it's running), and I also can't find any Registry entries that match their names. Here's what they look like (the three tasks at the bottom):





As you can see, the task gets a new name every day, and it never succeeds; I've tested it for a bit and noticed it'll always get 'stopped' when I turn off my computer. If I turn it back on, the task won't come back (only after roughly 9 hours have passed after the computer was turned on again). I've also checked the Task Manager logs in Event Viewer and found this - it always happens as soon as the task starts running:









I've tried googling "JD_TaskSchedulerSchedule" to find out what it might be, but there seems to be very little information about it. One person suggests these tasks can happen after installing "Trillian", and that they remain after the program has been uninstalled, but I'm fairly sure I've never installed this program on my current computer (though I did use it on my older laptop). I've already ran multiple full malware/virus scans (Malwarebytes, Windows Defender Offline, Avast, ESET Online, etc) and everything came up clean. My computer also doesn't show any other signs of infection, and I'd imagine this task would run at startup or at odd/unpredictable times, to camouflage itself, if it was really a virus, instead of always running after 9 hours have passed since Windows started running. I've also checked for unusual activity with Autoruns and TaskSchedulerView but everything seems to be in order, and I can't find any trace of this task anywhere else in the system. I've also already ran sfc /scannow and there are no corrupted Windows files in my system. I'm running Windows 10 Pro 1903. Is this something I should worry about, or just a regular Windows task? I'd really appreciate it if someone could explain these tasks to me, thanks in advance!
