Windows 11 tasks referencing MusNotifications.exe (which doesn't exist)

In checking tasks and the related results in Windows 11 Pro I've come across several tasks that did not complete correctly. I'll post separately for each of these issues to keep the questions/answers as simple and straight-forward as possible.

PC running- Windows 11 Pro version 22H2 OS Build 22621.2361

                Windows Feature Experience Pack 1000.22674.1000.0 installed on 8/19/2023

                (with any/all updates installed since)

This question refers to tasks related to running MusNotifications.exe stored under the C:\Windows\System32 folder.

There are 4 tasks listed, 2 are marked disabled.

The 2 that are still enabled both result in "The system cannot find the file specified. (0x80070002)".

The .exe file does not exist under the System32 folder. There are several references online, but I'm assuming more recent updates/upgrades to Windows/Office from Microsoft have eliminated the use of the .exe file.

It should also be noted that I have never modified any of the 4 tasks referencing this .exe.

If Microsoft has eliminated the .exe should they not have eliminated all related tasks that reference it?

Can I disable the 2 tasks still enabled without causing other issues?

Can I delete all 4 tasks referencing the .exe without causing issues?

Thanks

    Yes, I have full administrator privileges on this PC, but the task in question are owned by the SYSTEM account which I have no control over obviously. So no matter what I try to do with it, I can't as it always says I don't have the right privileges.

    If I try to simply disable it, I get an error message "The user account you are operating under does not have permission to delete this task."

    If I open the task and try to disable it under trigger settings, it requires me to enter the password for the S-1-5-18 account, which of course I don't have.

    And so on...

    I simply used the 'autoruns' tool to delete it.

    Thanks for the reply Emmanuel, but unfortunately when I tried to disable it it says I don't have permission to do so.

    Appears the permissions are given to the local system account and the best I can do is get it to say I don't have permissions to disable it or get it to pop-up a password entry box to type in the password for S-1-5-18...

    So this appears to be something that MS should have cleaned up when they decided to remove the .exe in the first place.

    In this case, do you lack administrative privileges on the computer you are presently using?

    Can you please explore the following links and examine the troubleshooting procedures to determine if any of them are relevant to your situation?

    Hello Eray, thank you for reaching out to the Microsoft Community. I am here to help and provide assistance with any questions or concerns you may have.

    If the MusNotifications.exe has indeed been eliminated, it would be logical to also remove all related tasks that reference it. However, this might not always be the case due to various reasons such as oversight or backward compatibility.

    As for your questions:

    1. Generally, if a task is trying to run an executable that doesn’t exist, it should not cause any issues if you disable it. The task is failing to complete anyway due to the missing executable.
    2. This could potentially cause issues if the tasks are re-created by a future update, or if they are needed for a feature that gets added later. It’s usually safer to disable tasks rather than delete them.

    If you’re unsure, it’s always a good idea to create a system restore point before making such changes.
