Free Utility/General Method to close Connections in Win10?

[WWGD]

Hi All,
The free Windows command-line untilities Netstat and Netstat -an alllow one to view all ports, connections used when surfing the web. Still, is there a way to _close_ any connection. I am interested in doing it within SQL Server, but I wonder if there is a more general way of doing it.
Thanks.

finds 457 000 000 references, probably something useful in that large a universe!

Thanks. Yes, I am being lazy in part, but the idea is for someone who has knowledge on this to help me filter through all the hits.

try tcpview from formerly sysinternals, now microsoft: https://docs.microsoft.com/en-us/sysinternals/downloads/tcpview
or CurrentPorts http://www.nirsoft.net/utils/cports.html This also has a command line option you could use from an sql stored procedure or sql server agent task
Of course many programs will just open another connection.
