There is a place in the windows Registery that works just like the startup folder in the start menu. Go to this Key in regedit.exe (to start regedit.exe, go to start->run and type in regedit.exe... Then you can either search for the key called RUN or you can find it here HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
you can also find in in the runonce key right below the run. To find out what value is loading that damn folder, look for something to do with C: my computer or something. You should be able to find it... If that doesnt do it, load regedit.exe and go to edit, then search for Run and run once... You can also remove annoying startup programs from the run key. BUT BE CAREFUL what you delete, because you could delete something needed for windows to run... Most of the stuff in the run folder is safe to delete, but just be careful and make sure you have your data backed up!!!
Hope this helps -Drew
