Which tool is used to diagnose and resolve connection issues in Windows?

The Network Troubleshooter is a built-in tool in Windows designed specifically to diagnose and automatically resolve a variety of network connection issues. When you encounter problems with your internet connection or network access, this tool can help identify common problems, such as issues with the network adapter, incorrect settings, or conflicts with other devices on the network.

When activated, the Network Troubleshooter will guide the user through a series of checks and tests, attempting to pinpoint the source of the problem and suggesting fixes or automatically applying them. This makes it a user-friendly option for those who may not have extensive networking knowledge.

While the other tools listed can contribute to network management or monitoring, they do not specifically target the diagnosis and resolution of connection issues in the same straightforward manner as the Network Troubleshooter. For instance, Network Monitor is primarily used for capturing and analyzing network traffic, while Device Manager helps manage hardware devices, and Task Manager is focused on monitoring system performance and running processes. Therefore, the Network Troubleshooter stands out as the most effective tool for directly addressing connectivity problems.
