If you want to block a program in the Windows 10 firewall, it’s pretty straightforward. You’ll need to access the firewall settings, create a new rule, and specify the program you wish to block. This ensures that the program can’t send or receive data through the network, effectively cutting it off from the internet.
Step-by-Step Tutorial on How to Block a Program in Firewall Windows 10
Blocking a program in the Windows 10 firewall will prevent it from communicating over the network. Follow these steps to accomplish this:
Step 1: Open the Control Panel
First, access the Control Panel. Click on the Start Menu and type "Control Panel," then press Enter.
Opening the Control Panel is your gateway to accessing various system settings, including the firewall.
Step 2: Navigate to the Firewall Settings
Click on "System and Security," then select "Windows Defender Firewall."
This will take you directly to the section where you can manage your firewall settings.
Step 3: Open Advanced Settings
On the left-hand side, click on "Advanced settings."
Advanced settings allow for more intricate control over the firewall, including creating new rules.
Step 4: Create a New Outbound Rule
In the new window, click on "Outbound Rules" on the left sidebar, then click "New Rule…" on the right side.
Outbound rules control the data leaving your computer, and blocking it prevents the program from sending out data.
Step 5: Choose the Program
Select "Program" and click "Next." Browse to find the specific program’s executable (.exe) file you want to block.
Specifying the program ensures that only the selected application is affected by the rule.
Step 6: Block the Connection
Choose "Block the connection" and click "Next."
Blocking the connection stops all network activity for the specified program, effectively cutting it off from the internet.
Step 7: Apply the Rule
Select when the rule applies (Domain, Private, Public) and click "Next." Name your rule and click "Finish."
Naming the rule helps you easily identify it later if you need to make changes or remove it.
After completing these steps, the program you specified will be blocked from accessing the internet.
