I am using Windows 7 as a user without admin privileges (with no chance to change this situation). I have quite a long list of tasks, which are actively managed (I'm adding, deleting and rescheduling them permanently). Each of them indicates a .bat file, which contain further instructions.
At the moment I have three tasks, which cannot be deleted, even though all of them have been created by me, using exactly the same user, exactly the same rights and one of them I tried to delete for a first time a few minutes after it had been created.
I'm trying both Task Manager and a proper schtasks command in CMD. The result is always "access denied" (CMD) or "user account have no privileges to remove the task" (TM). I was able to disable them, but I'd like to remove them from the list of tasks.
The problem occurs for these three tasks only. What is important here - all of my tasks have generally the same structure and properties. Most of them are being deleted without any problem. I cannot see any difference between the mentioned ones, which cannot be removed.
