How to Disable Google Update.EXE
The Google Update tool (Google Update.exe) connects automatically to the Internet and installs updates for Google applications. It is installed with several Google applications, including the Google toolbar and Google Desktop. Once installed, Google Update runs in the background, searching for and installing updates from the Google server. Because the Google Update is an extra process that consumes memory, disabling it can save system resources.
Click the Windows "Start" menu and click the "Control Panel." Open "Administrative Tools" and click "Task Scheduler."
Click "Task Scheduler Library" and select "GoogleUpdateTaskUser." Right-click this selection and click"Delete." Click "OK" to disable the Google Update task. Close the Control Panel.
Press the "Ctrl," "Alt" and "Delete" keys together and click "Task manager" to launch the task manager. Click the "Processes" tab. Scroll down the list of processes, click "GoogleUpdate.exe" and click "End Process" to disable the process. End any duplicate GoogleUpdate.exe processes. Close the task manager.
