  4. In the right sidebar, click on New Rule:
  5. On “What type of rule you want to create,” select Program.
  6. On This program path, click on Browse and find the .exe file of the game you want to block.
  7. Select Block Connection, then click on Next.
  8. On “When does this rule apply,” tick the Domain, Private and Public checkboxes and click Next.

You can use this same process for any other executable files or apps.
