GoogleUpdate.exe

You may find that GoogleUpdate.exe is always running on your computer if you're using an older version of the program or if certain Windows services, like Windows Task Scheduler, are not working as expected. This ensures that you continue to receive updates for your Google software.

GoogleCrashHandler.exe

GoogleCrashHandler.exe runs continuously on your computer if you've selected to send anonymous usage statistics and crash reports to Google for certain Google software, like Google Chrome. It helps send crash details to Google when your Google software unexpectedly shuts down. We use this data to help determine how to prevent these errors from happening in the future.

To stop GoogleCrashHandler.exe from running, turn off the sending of usage statistics and crash reports for all the Google software on your computer. Visit Google Help to find instructions on turning these reports off.
