Check Content

This requirement for "Allow pop-up windows on specific sites" is not required; this is optional. The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Content settings/Allow pop-up windows on specific sites" must be set to "Enabled". Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge "PopupsAllowedForUrls" must be set as follows: HKLM\SOFTWARE\Policies\Microsoft\Edge\PopupsAllowedForUrls\1 = mydomain.com HKLM\SOFTWARE\Policies\Microsoft\Edge\PopupsAllowedForUrls\2 = myagency.mil If configured, the list of domains for which Microsoft Edge allows pop-ups may be allowlisted.

Fix Text
