I am using it for over 15 years and it never had these severe problems as in the last 1 or 2 years. Around the time they unlocked it for non MSIE users it got worse.
@Enthousiast When I run the Windows Hide Update Tool to hide some driver updates, I always see this Silverlight update KB4481252 yet it's not actually being offered when I run Windows update so it's always in that list for Hide Windows update, shall I hide it as well or shall I manually install it?
I've always wondered why these (defender) updates were not included in their monthly updated iso images.
