This Setting is managed by your Administrator error message in Windows Security

System administrators can place some restrictions over some applications, and settings so that normal domain users can’t just alter the feature on their own. So, if have seen the “This setting is managed by your administrator” message on Windows Security or Windows Defender page, you can’t tweak its settings. There are some ways you can take care of this problem, but before you do that make sure to go through the warning message.

Warning – Network Administrators place these policies for a definite reason. If you have seen this message on your Office laptop/PC, don’t enact any of these solutions without proper administrative consent.
