error 2147750680 in task scheduler when changing day of task

Question

I had a scheduled scan with Defender, on a Thursday. I tried to change it to Monday. I was asked for a password (I'm not sure which password) and then got the above error. I had entered the only password I use for the machine (the one used at the Lock screen to log back in).
After discussion on the Community Forum, it appears that it is a security issue. I was advised to change permissions on C:\Windows\System 32. I'm not sure I'm allowed (or happy) to do that.
Any advice on what to do?
I have found a workaround, to create a new task, which, strangely, is allowed, and delete the old one (also, strangely, allowed). Why is modifying not possible?
Thanks

Hello Ed,

Thank you for your question and for reaching out with your question today.

Error 2147750680 (also known as 0x80041316) is a common error code in Task Scheduler that occurs when there's an issue with modifying or creating tasks. It often indicates a permission or security-related problem. Here's how you can address this issue:

**1. Run Task Scheduler as Administrator:**
   - Right-click on the "Task Scheduler" application and select "Run as administrator." This ensures that you have the necessary permissions to modify tasks.

**2. Check User Account Control (UAC) Settings:**
   - Make sure that your User Account Control settings are not set to "Never notify." This can impact your ability to make changes to system-related tasks.

**3. Use an Elevated Command Prompt:**
   - Open Command Prompt as an administrator (right-click and choose "Run as administrator").
   - Try creating or modifying the task using the `schtasks` command-line tool.
   - For example, to create a new task: `schtasks /create /tn "TaskName" /tr "TaskPath" /sc weekly /d MON`

**4. Check Group Policy Settings:**
   - There might be Group Policy settings that are affecting your ability to modify tasks. Consult with your IT administrator or review Group Policy settings related to Task Scheduler.

**5. User Permissions:**
   - Ensure that you have appropriate permissions on the task folder and any associated files or resources.
   - Verify that you have sufficient rights to create or modify tasks on your system.

**6. Malware or Security Software:**
   - Sometimes, overzealous security software or malware can interfere with task modification. Ensure that your system is free of malware and that your security software isn't blocking legitimate actions.

**7. Task Corruptions:**
   - It's possible that the original task had some corruptions. Creating a new task and deleting the old one, as you mentioned, is a viable workaround.

**8. Check Event Viewer:**
   - Check the Windows Event Viewer for any related error messages that might provide more information about the issue.

**9. Windows Updates:**
   - Ensure that your system is up-to-date with the latest Windows updates and patches.

Remember that modifying system tasks and files can potentially impact the stability and security of your system. It's always a good practice to proceed with caution and make sure you understand the implications of the changes you're making.
