Have you ever noticed how some Windows programs just seem to appear from nowhere? They're not listed in your StartUp group, but they turn up uninvited every time you boot your system.
These "phantom" apps are probably being launched via the Windows Registry. If you want to get down and dirty, take a look in the Registry under HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run. But if you would rather keep your hands clean, download StartUp Manager 2.0 from US PC World Online http://www.pcworld.com/software_lib/data/articles/system/5018.htmlStartUp Manager 2.0 provides a quick and easy way to take control of all your StartUps. It will tell you exactly what's being launched "behind the scenes" at boot up, and let you disable apps selectively. And best of all, it won't cost you a cent. It's freeware.
