Restraining a software by taking advantage of the firewall di Windows 10 it is a fairly simple operation to do but it is necessary to clarify the difference between incoming connection e outgoing connection depending on whether you want to apply a partial or full block. In particular, if you choose to suspend incoming connections, then the program can only send data over the Internet but not receive any. Conversely, by interrupting outgoing connections, the software can only receive data from the Internet but not send it.

That said, to proceed with the blocking of incoming or outgoing connections, just follow the steps listed below:

• Press on the search bar at the bottom left and type firewall.
• From the results that appear, click on the first one that would be Windows Defender Firewall.

In case of second thoughts, you can unblock incoming and outgoing connections simply by selecting once with the left mouse button the rule created a little while ago and choose Disable rule or Delete always from the section Actions that appears on the right.

How to block a program with the Windows 10 firewall completely

Should you wish to stop a software in complete manner, so by completely cutting off Internet access, you can stop both incoming and outgoing connections at the same time. It is possible to do this creating two new rules as indicated above for the same software for both outgoing and incoming connections.

Alternatively, take advantage of a second solution that we indicate below:

• Always aprite Windows Defender Firewall as indicated above (thus typing firewall in the search field) and this time press on Allow apps or features through Windows Defender Firewall which you can always find in the left sidebar to access the section Allowed apps.

• Complete the procedure removing the tick to the Private and Public boxes in correspondence with the name of the chosen software and confirm by pressing on OK.

In case the program you want to block is not present in the list, you can simply add it by pressing on Allow another app ... that you always find in Allowed apps. Then click on Sfoglia ..., select the executable file and follow the steps above. In case of second thoughts, however, you can completely unlock the software by ticking the boxes private e Public and confirming by clicking on OK.

What to do in case of problems

If you are unable to restore the incoming and / or outgoing connections of a program even after following the instructions given above, then we suggest you restore the defined settings di Windows Defender Firewall. To do this, simply click twice in a row on Restore default settings from the window of Windows Defender Firewall accessible as indicated above.

If you used a antivirus software third-party with integrated firewall, and therefore not Windows Defender, then, by accessing the window Windows Defender Firewall, you will see a notice saying "These settings are managed by the vendor application NAME ANTIVIRUS". In this case, it is necessary to manage the blocking and / or unblocking of connections from the antivirus firewall.
