Windows Firewall exclusions don't work anymore

We use RealVNC to remote into computers over our LAN. Windows Firewall is on
all of them, but we put exclusions for ports 5800 and 5900, which is what
RealVNC uses. No problems, everything worked great, until a couple of weeks
ago, when our WSUS server released a whole bunch of Windows updates to all
the computers on the network. So now we have to turn off Windows Firewall
tobe able to remote into the desktops, even though those exclusions are still
there. Does anyone know what update could have caused this to "break"?

Which updates were installed on the problem machines? What Windows versions
are you dealing with?
