I received a notification of a system critical update (KB4022405 I think, but i´m not sure), and it looks that when i updated with Policy mode Windows couldn´t update, revertig all changes. I just enabled learning mode, and Windows updated correctly.
I don´t know if Eset can do anything to fix the Windows updates with this mode, or if i can really add a rule to fix this, but I want tell this.
Thanks, i´ll wait for replies.
