Block Window Management permission on specified sites

Supported versions

  • On Windows and macOS since 123 or later

Description

Lets you configure a list of site url patterns that specify sites which will automatically deny the window management permission. This limits the ability of sites to see information about the device's screens. This information can be used to open and place windows or request fullscreen on specific screens.

For detailed information on valid site url patterns, see https://go.microsoft.com/fwlink/?linkid=2095322. Wildcards, *, are allowed. This policy only matches based on site origin, so any path in the URL pattern is ignored.

If this policy isn't configured for a site, then the policy from DefaultWindowManagementSetting applies to the site, if configured. Otherwise the permission will follow the browser's defaults and let users choose this permission per site.
