OK thanks for that.
The Registry Key is normal, so no issue there.
That leaves the possibility of an orphaned Task, or an existing Task being corrupted.
To verify whether a task is orphaned, you'd need to review Tasks via the Task Scheduler that have been created by third party programs; for example a security program that creates a task to scan your hard drive when idle.
Once you confirm which tasks you currently have which were created by third party applications, you can then review the Registry TaskCache to see if the records there match your list, or there are any extra values. An extra value would be your orphan and can be deleted.
If you
right-click on
Start and select
run then type
regedit and click
OK and click
Yes to
User Account Control prompt you can then in the
left pane of the
Registry Editor window expand the keys to this location:
HKEY_LOCAL_MACHINE
That ought to give you a quick list to Tasks you or a third party application created to compare with the list you made.
Inside the Registry Editor you will notice just above the
Tree key is another key named
Tasks. If you expand that Tasks key you'll see a long list of {alpha-numeric} IDS each of which points to the many tasks that are by default part of windows, but also may contain some third party items. If your error messages ever provided a {alpha-numeric} name of the Task not working, then it will be located here and can be
right-clicked > Deleted to resolve an issue.
