netsh advfirewall firewall add rule name= "deny tcp 21" dir=in protocol=tcp localport=21 action=block

netsh advfirewall firewall add rule name= "deny tcp 22" dir=in protocol=tcp localport=22 action=block

netsh advfirewall firewall add rule name= "deny tcp 23" dir=in protocol=tcp localport=23 action=block

netsh advfirewall firewall add rule name= "deny tcp 3389" dir=in protocol=tcp localport=3389 action=block  学习电脑

netsh advfirewall firewall add rule name= "deny tcp 5800" dir=in protocol=tcp localport=5800 action=block

netsh advfirewall firewall add rule name= "deny tcp 5900" dir=in protocol=tcp localport=5900 action=block

netsh advfirewall firewall add rule name= "deny tcp 137" dir=in protocol=tcp localport=137 action=block
