To delete an invalid task use Schtasks command

Open command prompt
type SCHTASKS /Delete /TN * /F this will delete all tasks.

In case you have creted some imp tasks you can backup it though by using
SCHTASKS /Delete /S system /U user /P password /TN "Start Backup" /F
SCHTASKS /Delete /S system /U user /P password /TN "Start Restore"
