Configure allowed app/extension types

Controls which app/extension types are allowed to be installed.

This setting white-lists the allowed types of extension/apps that can be installed in Google Chrome. 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.

Supported on: Microsoft Windows XP SP2 or later
