This requirement for "Allow specific extensions to be installed" is not required; this is optional. The policy value for "Computer Configuration/Administrative Templates/Microsoft Edge/Extensions/Allow specific extensions to be installed" must be set to "Enabled". Use the Windows Registry Editor to navigate to the following key: HKLM\SOFTWARE\Policies\Microsoft\Edge "ExtensionInstallAllowlist" must be set as follows: HKLM\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallAllowlist\1 = "extension_id1" HKLM\SOFTWARE\Policies\Microsoft\Edge\ExtensionInstallAllowlist\2 = "extension_id2" If configured, the list of extensions for which Microsoft Edge allows to be installed may be allowlisted. |
