What is one capability of Windows Network Diagnostics?

Windows Network Diagnostics is a built-in tool designed to help users troubleshoot and identify issues related to network connectivity. One of its primary capabilities is to reset a computer's network adapter. This function can be crucial when resolving problems such as inability to connect to Wi-Fi or local area networks, as it refreshes the network settings and may restore connectivity.

The focus of Windows Network Diagnostics is primarily on resolving network-related issues rather than addressing problems associated with hardware or software outside of network configurations. This allows for a streamlined approach to diagnosing connectivity problems efficiently. By resetting the network adapter, users can often clear any misconfigurations and restore their internet connection without extensive manual intervention.

While other options mentioned, such as identifying software issues, performing disk defragmentation, and checking for virus infections, are relevant to overall system maintenance, they fall outside the specific concerns addressed by the Windows Network Diagnostics tool. This distinction highlights the targeted functionality of the diagnostics tool within the broader context of maintaining a computer's health and performance.
