In this guide, we will show you the various methods to re-trigger the Windows Firewall Notification. While there are quite a few third-party firewall extensions and applications but for most users, it’s the built-in one that manages to checkmark their prerequisites. In this regard, when you launch any app for the first time on your PC, the firewall straightaway comes into action and will bring up a prompt asking whether or not you want that app to have access to the internet.
However, there could be a few instances wherein you end up clicking on an incorrect response, or in rare cases, the prompt didn’t even come up in the first place. While you have the option to manually tweak this setting and add/remove the app from the Firewall whitelist, however, that is usually quite a long route. Fortunately, you could re-trigger the Windows Firewall Notifications using a few nifty workarounds. And in this guide, we will show you how to do just that. Follow along.
