Even if you turn off updates, Google Update continues to check for new updates. If you need to stop Chrome Browser updates, you can turn off automatic updates and prevent users from manually updating the browser themselves.
(Example: C:\Windows\PolicyDefinitions\en-US) Download the appropriate Google Update policy template for your Windows network: Microsoft Windows Vista and later Microsoft Windows 7 and later supports both ADM and ADMX templates. Use an administrative template to install and define policies for Google Update.
