      Friday morning I tried a system restore to fix a Word 2010 click-to-run issue. I quarintined c:\progra~2\common~1\micros~1\virtua~1\cvh.exe when it showed up in my Panda Dome process monitor because before then I had never realized it ran every time Word. After some quick googling and realizing that Word c2r wouldn’t open with the file blocked I unquarantined the file (it was in Panda Dome’s lost&found folder but I never could get it to restore to its original location), which is what lead to an attempted system restore. The restore failed but I fixed the Word issue by letting Windows scan for the file after trying to open ms word. That seemed to be the end of my issues until I opened the task scheduler that night to make sure the Adobe Reader update task was disabled. When I opened TS i got this error message: The selected task “{0}” no longer exists. To see current tasks click Refresh. I clicked ok and instantly got this: Task scheduler service is not available. Task scheduler will attempt to reconnect to it. (The task scheduler service was and is running)  Again I clicked ok only to get the original “{0}” error message again. After clicking ok the third time the error messages went away but the task status pane said reading data failed. I decided to check the tasks to see if I could find anything wrong. The appid task, autochk, certificateserviceclient (more on that one in a second) mui and the systemrestore task would all throw up the “{0}” error message when clicked and then every task clicked would show up as being empty after that until the task scheduler is closed and reopened. But the certificateserviceclient will show its tasks after clicking ok on the error if it is the first error giving task clicked. I know this won’t be a simple fix but any help or direction will be greatly appreciated

      Have a look in Services tab (right click on the Task Bar, Task Manager) at the “Schedule” task. Is it running?

      cheers, Paul

        The schedule task is running, that’s what makes this even weirder because the way these errors make it seem is that the schedule task should be stopped and from what little I can tell I don’t think that ever happened.

      Try doing the System Restore again, but from Safe Mode. A lot of times this will work, if doing so failed under Normal Mode.

      If the above doesn’t work, then you and the experts here should look at this Technet article:

      Task Scheduler Corrupt Tasks

      All tasks are stored under System32\Tasks, and registry entries for them are stored under:

      HKLM\Software\Microsoft\Windows NT\CurrentVersion\Schedule\TaskCache\Tasks
