Apps open on login, but arent in startup

Windows XP Pro:
When logging into this particular pc (no matter who logs in) quite a few system tools launch, like Computer Mgr, Services, Event Viewer, ODBC Connections, .Net Config…
I have checked in All Users Startup, Default User Startup, each users startup. Startup is empty…I then checked the registry HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run and did not find any items there that would launch all these tools. I also checked HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run and found nothing.
I check the Services to see if there was any unusual services running (there are not)… I looked for any scripts that might be running on the local machine at login to launch these tools and found nothing…If anyone has any ideas of how to stop these programs from launching, I would appreciate the help.
Thanks
