When all else fails, what's the final resort to fix INET_E_RESOURCE_NOT_FOUND?

If basic troubleshooting steps fail, consider resetting your network settings in Windows 10. This can be done through Settings > Network & Internet > Status > Network reset. Be aware that this will remove saved Wi-Fi passwords and other network configurations, so you'll need to reconfigure them afterward. If the problem persists, it may indicate a more serious issue with your operating system or hardware, potentially requiring a system restore or contacting technical support.
