How to fix “Windows Firewall has blocked some features” on Windows 10?

Issue: I’ve left my PC idle for some time and it went on a sleeping mode. I was home alone, so nobody could touch it. 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!

Solved Answer

“Windows Firewall has blocked some features” is an error that may occur on any Windows OS version (10, 8, 8.1, 7, etc.). Windows Firewall[1] is an in-built Microsoft Windows application that filters information coming to the system from the Internet and potentially dangerous applications (PUA).

The “Windows Firewall has blocked some features” error is typically triggered by false Firewall rules or third-party VPNs, such as Hotspot Shield[2], Tunnelbear, VPNFilter[3], VPNTop, AdVPN, and others. In general, Windows Firewall is used for allowing or rejecting the connections under the domain, private, and public levels. The firewall is a basic security measure ensuring a secure connection between the two hosts via IP address, port, or WiFi.

Although the “Windows Firewall has blocked some features” error is not the most common one, people keep reporting in on Microsoft forum from time to time for many years. Although experts agree that the issue is most frequently triggered by a third-party VPN application, which hasn't been allowed in the Firewall, some people claim that this issue may be caused by virus infection. Therefore, we would strongly recommend scanning the machine with a reputable AV engine in the first place.

Besides, try to fix “Windows Firewall has blocked some features” error on Windows with the help of FortectMac Washing Machine X9 repair software.
