Configure allowed app/extension types

Controls which app/extension types are allowed to be installed and limits runtime access.

This setting white-lists the allowed types of extension/apps that can be installed in Google Chrome and which hosts they can interact with. The value is a list of strings, each of which should be one of the following: "extension", "theme", "user_script", "hosted_app", "legacy_packaged_app", "platform_app". See the Google Chrome extensions documentation for more information on these types.

Note that this policy also affects extensions and apps to be force-installed via ExtensionInstallForcelist.

If this setting is configured, extensions/apps which have a type that is not on the list will not be installed.

If this settings is left not-configured, no restrictions on the acceptable extension/app types are enforced.

Prior to version 75 using multiple comma separated extension IDs is not supported and will be skipped. The rest of the policy will continue to apply.

Example value:

hosted_app

Supported on: At least Microsoft Windows 7 or Windows Server 2008 family
