Autoruns for Windows [ http://technet.microsoft.com/en-us/sysinternals/bb963902.aspx ]
This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor, shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. This utility is a good compliment to Starter, and between the two, you can clear up almost any problem you are having with program startup.
