Understanding Firewall in Windows 10

Firewall is an essential component of any operating system that helps protect your computer from unauthorized access and potential threats from the internet. In Windows 10, the built-in firewall feature allows you to control which apps and programs can communicate with your computer both on the local network and over the internet. By blocking specific apps in the Windows 10 firewall, you can ensure that only the trusted and necessary applications have access to your system.

Why Block Apps in Firewall

There are several reasons why you might want to block certain apps or programs in the Windows 10 firewall:

• To enhance security: By blocking apps that are not essential or unknown, you minimize the risk of potential malware or unauthorized access to your system.
• To prevent network congestion: Some apps continuously communicate with the internet, consuming bandwidth. Blocking them frees up network resources for other critical tasks.
• To improve privacy: Certain apps may collect your personal information or send telemetry data. Blocking them ensures better control over your data.
• To reduce distractions: Blocking specific apps can help eliminate distractions and improve your productivity by preventing them from accessing the internet.

Step 4: Test the Blocked App

After creating the outbound rule to block the app, it's important to test whether the block is effective. Here's how to test it:

• Open the app you blocked in the outbound rule.
