Lock? You mean close? Or open?
Yes, close.


It's easy enough to add exceptions to the Windows Firewall (incoming
only - the windows firewall lets you communicate out without limits.)
Just add an exception if you want a given port opened. You can do it by
application or by specified port #.
Just vice versa - I'd like to permit, i. e. open, all ports except one,
which has to be closed. How to configure this effectively?

Thomas Wiedmann

In the network settings Advanced properties Windows firewall settings,
exceptions tab. You can locate your application and turn off the
checkbox for it. This should disable the application's ability to open
a port unless that application is a client or uses ephemeral ports for
outbound connections.
