Block Window Management permission on these sites
Supported on Microsoft Windows 7 or later
What it does
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

- Some Microsoft policies use built-in Policy CSP pages whose area names don't match the ADMX file name, so verify the candidate against Microsoft Learn before deployment.
