How to Troubleshoot and Fix Firewall Issues in Windows 10

Windows Firewall Issues

Even though the built-in Windows firewall works well to block popups in Chrome and so, there could be some errors or related issues in the program under certain circumstances. Sometimes, some remote assisting features or apps may not work because they might have been blocked by Windows 10 Firewall.
