Title

The ability of sites to show pop-ups must be disabled.

Control

The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Content settings/Default pop-up window setting" must be set to "Enabled" with the option value set to "Do not allow any site to show pop-ups". Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge If the value for DefaultPopupsSetting is not set to "REG_DWORD = 2", this is a finding.

Discussion

Set whether websites can show pop-up windows. Pop-ups can be allowed on all websites ("AllowPopups") or blocked on all sites ("BlockPopups"). If this policy is configured, pop-up windows are blocked by default, and users can change this setting. Policy options mapping: - AllowPopups (1) = Allow all sites to show pop-ups. - BlockPopups (2) = Do not allow any site to show pop-ups.
