Google Earth has been included as part of Google Pack, which has Google Updater as one of its core program. Google Update is a memory-resident and sit on system tray (notification area) application program that downloads and installs all the software selected in the Google Pack, beside monitoring the status (check for new version) of installed software, run software that’s been installed, or uninstall software.
