I found an answer to my own question.  I inserted Drivers and Utilities disk for my Dell Photo All-in-One Printer 964 and ran the program to update my existing printer files.  Lo and behold, when I restarted my computer which ends the re-installation, there was no file C:\program files \ dell at start up.  To everyone who gave suggestions, I thank you.  
I have tried going to HKEY_LOCAL_MACHINE \ Software \ Microsoft \ CurrentVersion\ Run but cannot find C:\ProgramFiles\Dell\Quickset, Dell Support, or anyting else that pertains to Dell other than my Dell All-in-one printer.  I have nothing in my Dell folder about startup when I go to Start - All Programs - Dell.  Does anyone have any other suggestions to rid the startup of C:\Program Files\Dell\ ?
C:\Program Files\Dell\ opens at startup
