I configured the Windows 7 disk defrag utility to run on the 1st of the month at 1:00 AM. The associated task gets created in the Task Scheduler and all is well until the next time I reboot my computer. Once I try to go into Task Scheduler after a reboot, I get the following message:
The selected task "{0}" no longer exists. To see the current tasks, click Refresh.
After clicking OK and browsing through the folders under Task Scheduler Library to try and narrow which task is corrupt, I always get the same message when opening Microsoft > Windows > Defrag. After clicking OK again, I can see the content of the folder is empty.
It seems as though the task is getting deleted, but some sort of pointer or reference to the task is still existing (causing the error to be thrown). I've had this behavior happen on three separate machines all running Windows 7 Ultimate SP1 with all available updates installed.
Has anyone seen or can anyone replicate this behavior? I understand there are other, better defrag options out there but this problem has me perplexed.
Disk Defragmenter was scheduled using another program
I can only remove the settings, which overwrites my manually-created task, or cancel.
