Information
This setting lets you decide whether to turn on Pop-up Blocker and whether to allow pop-ups to appear in secondary windows.
The recommended state for this setting is: Enabled.
Rationale:
The Pop-up Blocker serves an important purpose by blocking malicious popups and helping prevent the machine from being compromised.
Impact:
None - this is the default behavior.
Solution
To establish the recommended configuration via GP, set the following UI path to Enabled:
Computer Configuration\Policies\Administrative Templates\Windows Components\Microsoft Edge\Configure Pop-up Blocker
Note: This Group Policy path may not exist by default. It is provided by the Group Policy template MicrosoftEdge.admx/adml that is included with the Microsoft Windows 10 Release 1511 Administrative Templates (or newer).
Note #2: In the Microsoft Windows 10 Release 1511 Administrative Templates, this setting was named Turn off Pop-up Blocker, but it was renamed starting with the Windows 10 Release 1607 & Server 2016 Administrative Templates.
Default Value:
Enabled. (The Pop-Up Blocker is enabled, which stops pop-ups from appearing.)
