There are many tools out there which analyze and report on Windows start up applications, but what if you want to know a bit more information about these start up programs and whether or not you actually need them? If this is the case, check out Sysinfo.org which offers a searchable listing of start up processes.One thing to note regarding this list:

This is NOT a list of tasks/processes taken from Task Manager or the Close Program window (CTRL+ALT+DEL) but a list of startup applications, although you will find some of them listed via this method. Pressing CTRL+ALT+DEL identifies programs that are currently running - not necessarily at startup.

While this is not a 100% definitive list, it does have a huge listing of start up items (16,820) including those which are installed by viruses and other malware.This information may be a bit overkill for some users, but for power users or people who want to know exactly what is going on with their system this resource can be useful.
