I guess information security is different to PC security. If everybody was forced to run security updates there would be a huge reduction of viruses pushed out from the windows platform.
I understand the guts of my system but I have no idea about the guts of the code contained within a patch. I also understand that M$ does not releases critical patches unless they are critical.
Also as somebody confirmed on yet another Win10 thread, the updates are only compulsory on home edition, I didn't know this myself it's disturbing gold partners don't know either.
