Windows XP, Windows Vista, and Windows 7 come with built-in security software, also known as Firewall, that lets you block or allow network access to specific applications. There is a special algorithm for activating protection.
Instructions
Step 1
Find the folder with the executable file of the program you want to block. If you need to find it by a shortcut, right-click on it and select "Properties". The field named "Location" contains the path to the executable file, the name of which will look something like this: "C: / Program Files / Game / Gamefile.exe". From here you can go to the required folder.
Step 2
Click the Start button, then Run, enter the text "wscui.cpl" without quotation marks, and press Enter. This will launch Windows Security Center. Make sure On (or Enabled) is enabled, and then select Windows Firewall. If protection has not been enabled, select the General Settings tab and click On.
Step 3
Select the Exceptions tab and scroll through the list of programs and services. If the program you are interested in is in the list, uncheck the box next to its name by clicking on it. This will block the program. If necessary, uncheck the box next to "Display notification when Windows Firewall blocks a program" to block the program without notifying the user.
Step 4
Add the required program to the list if it is not there. Select Add, then Browse. Navigate to the desired folder, select the executable file (*. EXE) and click "Open". The program will be added to the firewall list. Make sure the added program is on the blocked list. Scroll through the list, find it and uncheck the box next to it to activate the lock.
