HKLM\Software\Policies\Microsoft\Edge
This setting controls whether Microsoft Edge sends data about blocked extensions to the Microsoft Edge management service. The 'EdgeManagementEnabled' policy must also be enabled for this setting to take effect. If you enable this policy, Microsoft Edge will send data to the Microsoft Edge service when a user tries to install a blocked extension. If you disable or don't configure this policy, Microsoft Edge won't send any data to the Microsoft Edge service about blocked extensions.
