HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Google\Update
Add a new DWORD value named DisableAutoUpdateChecksCheckboxValue and set it to 1 to disable automatic updates or 0 to re-enable them.
Mac OS X
Open terminal and run the following command:
defaults write com.google.Keystone.Agent checkInterval 0
To re-enable automatic updates for google chrome use this command:
defaults write com.google.Keystone.Agent checkInterval 1
This also works for Chromium and beta versions of GoogleChrome.
