Error message 'The selected task "{0}" no longer exists. To see the current tasks, click Refresh’
A lot of customers complained the following:
When they open up the Task Scheduler, they get a message that says:
The selected task "{0}" no longer exists. To see the current tasks, click Refresh.
The mechamism task scheduler uses: it has a copy of tasks in registry and a copy of them in task files on disk. If somehow the tasked stored in registry and on disk are not in sync, users will encounter such issues as reported.
Tasks are stored in C:WindowsSystem32Tasks
In Registry, related branches are located in:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTasks
Tasks tree is stored in:
HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionScheduleTaskCacheTreeMicrosoft
So the general troubleshooting steps are starting from checking these locations to see if anything is broken or inconsistent.

If It can be fixed by a series of steps then surly MS could generate a EXE or BAT file which would fix a complicated error. The semi-automatic fixing of errors is one thing which possibly would create a user friendly os.Anonymous

- Open Registry Editor
- Open the following Key a. [HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrentVersionTracingSCMRegular]
- Add/Change the following value a. Name = TracingDisabled b. Type = REG_DWORD c. Value Data = 0
- Reboot the Server
- Open Task Scheduler and verify that you can see the tasks

Thanks to Abhishek for his suggestion - Seems to be a system logging system. I was unable to find which task in the Windows folder was causing the problem as they ALL gave an error. Followed Abhishek idea and was then able to find Defrag was the problem. I deleted the file from my HD and the problem was cleared. Then un-did the Abhishek fix.Anonymous

Same issue here, scheduler worked but after awhile the message starts to grate on my nerves...
Problem was corrected by simply resetting the schedule for the defrag then disabling it in the scheduler, apparently I deleted it...Anonymous

I had this issue today, came across this thread and looked at the solutions. I managed to solve my error with just a restart of the Task Scheduler service. It might be worth that a go before messing with the registry / rebooting server.Anonymous
