I have been running Windows 10 for about a month, recently I have received two pop-up the following one for the first time today. Windows Firewall has blocked some features on all public and private networks. I managed to get a copy of this message (see attachment) Before I had a chance to click on the option of ALLOW or Cancel it went off screen. What's it all about? I have a total of three computers on this network that are running at the time (2 x PC on Windows 7) and one Toshiba that had been updated from Windows 7 to Windows 10 (a bout a month ago) I will post a further Thread for the other pop-up shortly.
