  1. Hidden Task Revealer


    In Windows 10 "Task Scheduler" strangely named tasks of the form {c092b15a-a322-4688-630fe8d1a911} can be observed occasionally in the Task Status section which is a log of tasks executed (as shown in the screenshot below).

    This was also observed at the following links

    Oddly named tasks in Task Scheduler?
    Random weird scheduled tasks - Windows 10 Support

    This task isn't revealed on any of the other task scheduler subitems.

    A search of the "Event Viewer" task scheduler xml logs for {c092b15a-a322-4688-630fe8d1a911} gives an ActionName of

    However the name "JD_TaskSchedulerSchedule" isn't found in any of the Windows 10 "Task Scheduler" items.

    This was observed at the first link above and also at the following link.

    What is "JD_TaskSchedulerSchedule"?


    Some of the previous web links suggest a program called Trillian (a chat program) could be responsible but as this has never been installed on my machine this eliminates this possibility.

    After some investigation I found that the task identified above originates from the OneSyncSvc service (formerly known as ActiveSync). This service uses the WpTaskScheduler.dll library module to add tasks to the Windows task scheduler and generates a random GUID, the {c092b15a-a322-4688-630fe8d1a911} part, for the task name of every task it creates.

    The actual schedule name is of the form SimpleActivityScheduleTimer_{xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx} where xxxx...x is a random GUID.

    It is confirmed to exist by default on Windows 10 Home version 1803 and 1909 and probably exists on other versions of Windows 10 as well.

    This task executes every 12 hours after a reboot. Therefore you will have to wait 12 hours after a reboot to see it in the
    Task Scheduler Task Status section.

    I actually don't know what this task does but I'm guessing it probably is used to clean up OneSync/ActiveSync.

    Some further info about my investigations is provided at the following link.

    It was an answer to the first post above which was cross posted to the following link.


    After getting this far I decided to write a program to reveal these tasks. This is useful from a security point of view.

    The program I have created is called WpTasks.exe and is currently a Windows Console program (Cmd.exe).

    It displays all of these tasks and can also provide more info on each of these tasks.

    It also has the option to delete them.

    More info on this program is provided by the README at the following link.

    A zip file containing the executable and the README can be downloaded from the following link.

    The program is free to use.

    Source code isn't currently availiable.


    Please use this forum thread to provide feedback on this. If I'm working on something else I may be slow to reply so please be patient.

    I'm particularly interested in the following feedback on the program:

    1) What other versions of Windows 10 other than Windows 10 Home 1803 and 1909 use or do not use these tasks.
    2) If you observe schedule names other than SimpleActivityScheduleTimer_{xxxxxxxx-xxxx-xxxx-xxxxxxxxxxxx}.

    I will post any notice of updates to this thread. The download link will probably remain the same for updates.

    NB For other websites if you provide a direct link on your site to the download please include a link to this thread to inform and encourage feedback from users.

    Hope you find this useful.

  2. All hidden files turned Un-hidden


    Thank you for posting in Microsoft Community and being part of Windows 10.

    I suggest you to re-add them to the hidden items list and check.


    • Right click on the folders to hide, select Properties.
    • Go to General tab, under Attributes check mark the option
    • Click on Apply and on Ok.

    I suggest you not to use any third party anti-virus software. Try to use Windows Defender.

    Refer: Using Windows Defender

    Hope it helps. Feel free to contact us for further assistance on Windows Operating System, we will be happy to help you.

  3. Auto Shutdown using the Windows 10 Task Scheduler not shown in the Task Scheduler Library

    1. Yes I am the administrator and I am Log On as the administrator. I am also the only user of this computer. A check under user accounts shows my administrator account is only account on the computer.

    2. A check of Show Hidden View status revealed it was and is check marked. The list of Task remains unchanged with the check mark on or off.

    3. Installation of Auto Runs did not reveal any task that did not appear before. It's results were identical to the task scheduler library.
