How to close all ports in windows 7?
preferably by standard means without third-party software.

Answer 1

Unfortunately, I don’t know how to block all ports, but you can try using a dash, that is, 1-49151
command
netsh advfirewall firewall add rule dir=in action=block protocol=tcp localport=(port) name="Block_TCP-(port)
or you can spam this command in a batch file and change only the port
number.Software is easier.

Answer 2

Regular Windows firewall - a rule for incoming traffic - set to block.
You can also use external firewalls, for example, on a router.
