- From start menu, search for "Firewall" and select Windows Firewall with Advanced Security
- Choose Outbound Rules from the tree at the left.
- Choose New Rule... from the menu at the right.
- New Outbound Rule Wizard opens. This is really easy now:
a. Select Program as rule type.
b. Select the program's EXE file.
c. Choose Block the connection.- Choose the profile this rule applies to. If in doubt, select all three.
- Add the descriptive name (you may want to delete this rule later).
