Internet Explorer is part of the OS so you can delete the shortcut to it and ignore IE.
Google is a web site and services that are not yours to control so you may choose to ignore and not use their services but "Google" is not an app to be removed from your PC.
How can I delete Internet Explorer and Google from my computer? I am running MS Vista, but when I go to the Control Panel and open the folder for installing / uninstalling programs, neither program is listed. Thanks.
