MSCONFIG on steroids - Another great Utility from Sysinternals

Autoruns


"This utility, which has the most comprehensive knowledge of auto-starting locations of any startup monitor (A starting list of auto-run locations was obtained from David Solomon's "Windows Internals" seminar), shows you what programs are configured to run during system bootup or login, and shows you the entries in the order Windows processes them. These programs include ones in your startup folder, Run, RunOnce, and other Registry keys. You can configure Autoruns to show other locations, including Explorer shell extensions, toolbars, browser helper objects, Winlogon notifications, auto-start services, and much more. Autoruns goes way beyond the MSConfig utility bundled with Windows Me and XP."
