Windows Firewall is a security program built by Microsoft which can be software based or hardware based. It is built into Windows XP, Windows Vista and Windows 7 by default and protects the system from network malwares and unauthorized modifications. Windows Firewall can block or allow network access to specific application. When it blocks certain applications or websites, the user won’t be able to install that application or access that website in their computer with the Windows Firewall turned on. Based on the program’s file name, specific TCP or UDP ports, or communication protocols such as HTTP, access can be allowed or blocked.
Here’s how you block application using Windows Firewall, without having to dial any Windows support number:
Windows support instructions to block using Windows Firewall
- Verify the executable file name of the program to be blocked. Right-click and choose “Properties” On the program shortcut. In the box named “Target” you can find the executable program. You can see the file name in a format similar to this: “C:\Program Files\Game\Gamefile.exe.” Note this folder location and file name.
- Click the “Start” button from the bottom left corner of the computer screen, in the “Run” box, type the text wscui.cpl and press “Enter.” This will open the Windows Security Center. Check whether the Firewall is set to “On,” and then select “Windows Firewall.” choose the “General” tab and click the “On” radio button if the Firewall was not on.
- Select the “Exceptions” tab and scroll down through the Programs and Services list. Remove the check mark from the box beside the program name if the program is on the list by clicking it. The program is blocked when you clear this box. To have the program silently blocked with no notification to the user remove the check mark from “Display a notification when Windows Firewall blocks a program“.
- If the program is not on the “Exceptions” tab Program and Services list, add the program. Select “Add Program” and from the “Programs” list, highlight the program. Click “Browse” If the program name is not on this list either. Browse to the location you noted in first step, select the executable (*.exe) file and press “Open.” The program is now on the “Programs” list. Click on its name to highlight and click “OK”.
- Verify if the program is on “Exceptions” tab Program and Services list. Scroll down, find the program that you just added and remove the check mark from the box. The program is blocked once you clear this box.
With these well- listed steps you won’t need to dial the Windows support number to get your process done. Thank you!
