3. Install apps

You can automatically install Chrome apps and extensions on your users' Windows computers. You can also control which apps or extensions they can install themselves. To install apps in the cloud, you can use Chrome Browser Cloud Management.

Set a default policy (Extension management settings) for all apps and extensions. Then, if you want to customize a specific app or extension, you override the default settings.

Use Group Policy

In your Microsoft Windows Group Policy Editor (Computer or User Configuration folder):

1. Go to Administrative templatesGoogleGoogle ChromeExtensions.
2. Enable Extension management settings.
3. In the box under Options, using JSON code, set the installation mode to:
   • allowed—Users can install apps and extensions from the Chrome Web Store. If no installation mode is defined, this is the default.
   • blocked—Users can’t install apps or extensions from the Chrome Web Store. You can define a custom error message that lets users know it’s blocked (details below).
   • force_installed—Automatically install extensions that you specify without user interaction. Users can’t disable or remove them. You also need to define the extension download location (details below).
   • normal_installed—Automatically install extensions that you specify without user interaction. Users can disable them. You also need to define the extension download location (details below).

Note: Enter the JSON code as a single line with no line breaks. We recommend that you use the JSON validation tool of your choice to pre-check your configuration and compact it into a single line. See the example below.

Example JSON
{ "*": { "runtime_blocked_hosts": ["*://*.example.com"], "blocked_permissions": ["usb"]    } }
Compact JSON
{"*":{"runtime_blocked_hosts":["*://*.example.com"],"blocked_permissions":["usb"]}}
