|When you deleted the files or HP folder, you have prevented the add-remove feature from being able to remove what is left of the program which is mainly the registry entry. If the computer will run normally and print normally, it may be best to ignore the fact that it is still there. If it creates any issues or you would just like to fix it, you will need to reinstall the software, restart the machine, and then uninstall it again. You can download the software from HP's site.|
You have to be a little bit crazy to keep you from going insane.
