Forgive my ignorance. What is the event viewer?

I've used CCleaner on my xp computer many times and never had a problem. This is the first time I've used it with vista. I ran CCleaner and I went through the registry errors one at a time. They were all related to uninstalled software. Anyway, now whenever I shut down /restart I get this error message- schtasks.exe failed to initialize (number X number) Click ok to close. Thanks in advance for any ideas.
