I think I understand your question, and it actually made me curious to view the list of LOLBins being blocked in FirewallHardening.
if you look at the list of LOLBins blocked in FirewallHardening, it can be seen that Andy has carefully chosen only those that will not break Windows functionality when they are blocked. Microsoft in their infinite wisdom has created an absolutely mind boggling myriad of rules in latest Windows versions for both inbound and outbound networking, most of which are not required for most home users. Things were so much simpler in XP days, made increasingly more complex with each Windows release since then.
As
@Kongo mentions above, keeping logging enabled, especially if you perceive network breakage for something is happening, can be very useful for narrowing down the problem.
