The description can be written according to your desire, this is done for convenience. Now click Finish and our rule will appear in the Firewall list.

Many software products require an internet connection to work. You do not pay attention to this fact until the connection deteriorates - sites open slowly, everything slows down.

In the next step, select "Block the connection" and click "Next".

Now similar actions need to be done for an outgoing connection. Select "Rules for outgoing connection" in the left part of the utility. Then, on the right side of the application, click on “Create Rule”.

The process of creating a rule is identical to that described above for an incoming connection. Repeat all steps above for the same program.

When the appropriate rules for the program are created, both for outgoing and incoming connections, the application will no longer have access to the Internet.

If you need to allow the program access to the Internet again, just go back to the Windows firewall, find the rules you created in the list of rules, then select them and click "Delete".
