I accepted the WIN10 upgrade and things have gone quite well until this week.  For no apparent reason, I have been receiving notices that Windows Defender has been turned off by group ploicy.  The notice tells me to contact my security administrator.
I am running WIN10 Home edition, and from what I can find out, it does not have a security administrator, and the only group I am aware of is my home Wi-Fi.  I am the owner of the desktop and the notebook, and am the "administrator" in both machines.  Granted, I am undertall for my weight, but I am not big enough to constitute a group.
Would anyone be able to suggest why I suddenly have this trouble?  Not knowing at all, but could it be some error in the resetting of permissions with the Tweaking free version?  I simply am not tech savvy enough to be able to figure this one out.  Any help or recommendations will be appreciated.
