Yes you can do it very easily. If the download has been installed on your system then you can uninstall it. All you have to do is to go to the "control panel" and then go to "add or remove programs". Go the the system you installed in your pc that must be with the title of "kane BT taskbar remover". There would be a icon of having title"remove/change" opposite to the title of software. Remove it by clicking on remove. The taskbar software will start removing from your system and your system will be automatically shifted to the previous state.
If you are having further problems with this you can ask a question again.
