Setting the policy controls extension management settings for Google Chrome, including any controlled by existing extension-related policies. This policy maps an extension ID or an update URL to its specific setting only. A default configuration can be set for the special ID "*", which applies to all extensions without a custom configuration in this policy. This policy can override per-extension config from legacy policies. Note that any per-ID extension setting from either ExtensionInstallForcelist, ExtensionInstallAllowlist, ExtensionInstallBlocklist, or ExtensionSettings will only inherit 'installation_mode' and 'update_url' from the "*" defaults. It will not inherit any other properties. With an update URL, configuration applies to extensions with the exact update URL stated in the extension manifest ( http://support.google.com/chrome/a?p=Configure_ExtensionSettings_policy ). If the 'override_update_url' flag is set to true, the extension is installed and updated using the "update" URL specified in the ExtensionInstallForcelist policy or in 'update_url' field in this policy. The flag 'override_update_url' is ignored if the 'update_url' is a Chrome Web Store url. On Microsoft® Windows® instances, apps and extensions from outside the Chrome Web Store can only be forced installed if the instance is joined to a Microsoft® Active Directory® domain, joined to Microsoft® Azure® Active Directory® or enrolled in Chrome Enterprise Core. On macOS instances, apps and extensions from outside the Chrome Web Store can only be force installed if the instance is managed via MDM, joined to a domain via MCX or enrolled in Chrome Enterprise Core. Note: This policy only applies to platforms that support extensions. See https://chromeenterprise.google/policies/?policy=ExtensionSettings for more information about schema and formatting.

Registry

BETAConfigure the state, scope and options, then generate .reg, PowerShell, Intune and SCCM outputs — or add the setting to a multi-setting collection.
These exports write the registry — this is not a managed GPO. ⓘ
Applying both scopes creates an ambiguous configuration (computer takes precedence over user). Only do this intentionally.
