Block Window Management permission on these sites

Verified with Google Chrome — updated on July 10, 2026

Supported on: Microsoft Windows 7 or later

Path in the GPO console

Computer Configuration\Administrative Templates\Google\Google Chrome\Content settings

Description

Allows you to set a list of site url patterns that specify sites which will automatically deny the window management permission. This will limit the ability of sites to see information about the device's screens and use that information to open and place windows or request fullscreen on specific screens. For detailed information on valid site url patterns, please see https://chromeenterprise.google/policies/url-patterns. Wildcards, *, are allowed. This policy only matches based on origin, so any path in the URL pattern is ignored. If this policy is not set for a site then the policy from DefaultWindowManagementSetting applies to the site, if set, otherwise the permission will follow the browser's defaults and allow users to choose this permission per site. This replaces the deprecated WindowPlacementBlockedForUrls policy. Example value: https://www.example.com [*.]example.edu

What to embed
Theme

Adds one script line: the theme follows your site’s appearance and the height fits the content. If your site blocks scripts, the embed follows the visitor’s system theme.
