Check the “This program path” box and click Browse. . . . Click This PC on the left side of the window. Scroll down and double-click your hard drive’s name (e. g. , OS (C:)). Double-click the Program Files folder. If the program you want to block is elsewhere, go to the program’s folder instead. Find the folder for your program, then double-click the folder. Select the program file by clicking it once.
If the program you want to block is elsewhere, go to the program’s folder instead.
This is necessary because Windows will restructure the path to the file once you open the file in Firewall, thus breaking your outbound rule. You can bypass this problem by manually pasting in the path to the file.
For example, if you wanted to block Chrome in the path “C:\Program Files\Google\Application\chrome. exe”, you would select all but the “\chrome. exe” section and replace it with your copied text. Leaving the app’s name and extension at the end of the path is crucial, as failing to do so will leave you with a rule that doesn’t block anything.
For example, if you’re blocking Google Chrome on your computer, you might name your rule “Chrome Block” here.
You may have to click Yes on a pop-up window after doing this before you can continue. If you don’t have administrator privileges on your computer, you won’t be able to do this.
Click Allow another app. . . below the list. Click Browse. . . . Go to the location of the app or program file (usually an EXE) that you want to block. Select the app or program file. Click Open, then select the program’s name in the window and click Add if it doesn’t automatically add.
If there is no checkmark to the left of the program, Windows Firewall is already blocking the program. Leave the two checkboxes to the right of the program (“Home/Work (Private)” and “Public”) alone.
