In order to remove the applications from your computer, navigate to Start > Control Panel > Uninstall a program, select the software from the list and click the Uninstall button. Follow the on-screen instructions and reboot your computer after the process is complete.
If you have issues, you can remove the software using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
