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 what extension load into various Windows processes, including Explorer and Internet Explorer. A "Hide Signed Microsoft Entries" option helps you to zoom in on third-party auto-starting images that have been added to your system.
You'll probably be surprised at how many executables are launched automatically!
Autoruns works on Windows XP and higher, including 64-bit Windows.
Note: before you send e-mail reporting what you believe to be an auto-start location that's overlooked by Autoruns, please make sure that Autoruns doesn't cover it and verify that the location actually works.
