HKLM\Software\Policies\Google\Chrome
Enables component updates for all components in Google Chrome when not set or set to enabled. If set to disabled, updates to components are disabled. However, some components are exempt from this policy: updates to any component that does not contain executable code and is critical for the security of the browser will not be disabled. Examples of such components include the certificate revocation lists and subresource filters.
