Googleupdate.exe uses about 1.6 Megabytes of computer memory while running. This might not be much on computer systems that have Gigabytes of computer memory but can make a difference on low end systems. There is however another aspect that requires some attention. Googleupdate.exe will send data to the Google server whenever it checks for updates.

This data includes a unique ID number, languages, operating systems, version numbers and other install or update related details. Disabling the googleupdate.exe process is thankfully not complicated. The process can easily be killed at any time and will not appear again in the process list during that session.

The Google Update process is added as a service during the first installation of a Google software that makes use of it. To change its behavior one would simply open the services configuration with [Windows R], [services.msc] and hitting [enter]. The service is called Google Update Service (gupdatexxx) with xxx being a random ID)

A double-click on GoogleUpdate.exe will open the properties of the services with the option to change the startup type from automatic to disabled.

A click on the apply button will change the setting and ensure that Googleupdate.exe will not be started during Windows startup anymore. Another click on Stop will stop the process for the current session.
