back out of changes via restore?

message from =?Utf-8?B?SmFu?= on 3 Jun 2004
I dutifully did a backup of my system files and C drive before installing a new application onto the C drive. The installation failed. I ran restore on my system files and C drive but I still see services, start menu items, and folders/files that were created by the failed application install. How should I proceed to remove these?
