I know how to disable the entire network adapter, but is there also a command in cmd that I can use to easily switch on/off internet access to specific processes, E.g. Zoom.exe? Understand I can do it via Firewall settings but I prefer a CMD method.

Thank you.

And another for specific app, you can use Windows Firewall through output rule (example for skype):

netsh advfirewall firewall add rule name="Block skype" dir=in action=deny program="C:\program\skype.exe" enable=yes

Yes I just need this. Is there a parameter I can use to just indicate the process name instead of the process path? Thank you.

Similarly, if I want to remove the rull, do I change "add" to "remove"?

Lastly, can I enter the command WITHOUT a rule name?

Hi!

1. for stoping running process, i suggest command dos TakKill ( in command prompt, type "TaskKill /?" to know all the attached parameters
2. Yes, "delete" instead of "add" kill the rule.
3. rule name is necessary in nstsh command, but you can use blank.

Hihi, I tried blocking Firefox with this command but I can still do a google search on it. Why so?

You want to block out not in. Hardly any app uses in, though Firefox uses it for TCP loopback. :unsure:
Code: 
netsh advfirewall firewall add rule name="FF Block In" protocol=TCP dir=in action=block program="%ProgramFiles%\Mozilla Firefox\Firefox.exe"
netsh advfirewall firewall add rule name="FF Block TCP" protocol=TCP dir=out action=block program="%ProgramFiles%\Mozilla Firefox\Firefox.exe"
netsh advfirewall firewall add rule name="FF Block UDP" protocol=UDP dir=out action=block program="%ProgramFiles%\Mozilla Firefox\Firefox.exe"
Why do not you use something like Firewall App Blocker (Fab) v1.7 ? It allows a simple CMD input.
Code: 
Fab.exe /a %ProgramFiles%\Mozilla Firefox\Firefox.exe
