If you uncheck both boxes next to an application, it won’t be allowed to connect on either Public or Private networks. Locate the application in the list, and then click the Public or Private checkboxes to control whether it’s allowed or disallowed, respectively.
To do so, head to Control Panel > System and Security > Windows Defender Firewall > Allow an app or feature through Windows Defender Firewall.Ĭlick “Change Settings” to unlock the settings. The Windows Firewall doesn’t ask you twice about the same application, but you can change the setting to allow or disallow any app in the future.

Run a scan with your preferred antivirus program if you’re concerned your PC might have malware. Some types of malware function as a server and might trigger a firewall alert. If you don’t recognize the application, you might want to search the web for the name and find out more information. So, you might not be able to host multiplayer games in a PC game, as the firewall blocks incoming connections. If you don’t allow access, an application might not function properly. A BitTorrent client, for example, needs this access to upload data to other systems on the internet. If you see this prompt and want to use a media server to share your media with other systems on your network, you likely have to allow access to do so. If you disallow access for a PC game, you might not be able to host multiplayer games. If you trust an application and want to use all its features, you should allow access. You can change this option for a network later in the Control Panel or Settings app. When you connect to a network, you choose whether it’s public or private- Windows doesn’t automatically know. People on your home or work networks, however, will still be able to connect. That way, when you connect your laptop to public Wi-Fi, no one can connect to your media server. For example, you might allow a media server application only on private networks. You can also choose which types of networks you want to allow the connections on. Or, you can click “Cancel,” and the firewall continues to block incoming connections for that application. You can click “Allow Access” and allow incoming connections through the firewall. When this box appears, you have a few choices.
On Windows 7 and 8, you see the “Windows Firewall has blocked some features of this app” message instead. On Windows 10, you see a “Windows Defender Firewall has blocked some features of this app” pop-up. This ensures connections aren’t silently blocked without your knowledge. You can then choose whether to allow the connection through. But the first time it blocks connections to a new application, this message pop up. The Windows Firewall blocks incoming connections by default. You only see it with specific types of applications, such as media servers, games with multiplayer features, online file-sharing tools, and other server applications. You don’t see this prompt for most applications you use, like web browsers and email clients. Disable any proxies that may interfere with the login module.This message appears when an application wants to act as a server and accept incoming connections.
