However, when I woke my PC up from sleep, I’ve found a message box saying: “Windows Firewall has blocked some features of this app. ”While I’m using my PC every day, I’m not a very technology inclined person, so I don’t know what I could do. Could you please provide me fixes in a very comprehensive manner? Would highly appreciate your help!
