Prelez si to ešte tu: C:\Windows\System32\Tasks

V registroch zmaž HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache
- predtým si kľúč zálohuj/vyexportuj !!!

Iný návod:

1. Open the Task Scheduler Library.
2. Open Microsoft
3. Open Windows
4. Click on every folder until you get the code. (in my case it was the Defrag folder)
5. Open up "My Computer" and in address bar type (or copy and paste) C:\Windows\System32\Tasks\Microsoft\Windows\
6. Click on the folder that gave the error in the Task Scheduler
7. Delete what is INSIDE the folder....NOT the folder its self.
8. Go back to Task Scheduler and enjoy no error!
