How to block Internet connection of Windows 10 software and applications

If you are connected to the Internet, almost any application can access the network connection without much difficulty. Of course, applications connect to the Internet to provide additional features or services, send telemetry information, and receive updates.

While allowing applications to access the Internet without any restrictions is not a big deal, there may be situations where you need to block or prevent a program from doing so.

In addition to antivirus software to protect computers from dangers, Windows has a built-in Windows Firewall to protect the system from external dangers. And during use, users can customize Windows Firewall to turn on or off to suit their needs. Or you can block Internet connection of any application or software through Windows Firewall.

We can block Internet access for any application or software on the computer, while other programs can still access the network. The following article will guide readers on how to disable Internet access for software and applications on Windows.

Things to note

The procedure below only works for regular win32 programs. If you want to restrict modern Store or UWP apps, you should enable metered connections . Metered connections (internet connections with a data limit attached to them) restrict updates and internet access in the background.

Although the whole configuration is quite easy, you should follow the steps carefully. Don't touch anything else unless you know what you are doing.
