Ran into this one today too. Someone customized the Task Scheduler in Windows 2008 R2 to remove the Action and View items along the top and then used customize on the Actions Pane to remove the Actions pane itself. Task Scheduler starts with just an empty screen now. Led to the answer from this page, removing a file called tasksched or something like that from the %appdata% path and restarting Task Scheduler did the trick. Stupid users.
