win explorer opens auto when logging in

after installing hp 7650 scanner I end up with a window popping up every time I log into windows. It is just a win explorer window that displays the folder c:\program files\hp\. All I do is close the window and go on. I did not use the CD that came with it initially. I downloaded the “corporate drivers” from HP’s site. This made the scanner work but did not have all the extras with it. I then downloaded and installed the Image Zone software that fives you full functionality. Upon rebooting and logging in window started appearing. After numerous uninstalls, deletions and registry removals I found the CD that came with it. I used it but am still getting the window opening upon logging in. Any ideas???
Thanks…
