Operating System Troubleshooting

Correct Answer: Use system restore

The best answer is to use System Restore. System Restore allows you to rollback your computer to a previous state before the problematic software was installed, which should resolve the issues caused by the software. Formatting the hard drive is too drastic and would result in data loss. Changing the registry can be risky if done incorrectly and may not resolve the issue. Disabling startup programs will not address the core problem of the malfunctioning software that cannot be uninstalled normally.

Correct Answer: Run a malware scan

Running a malware scan is the most direct approach to identify and potentially remove the malware. Other options may be more time-consuming, less effective, or could cause additional problems.

Correct Answer: Network adapter settings

The first step in troubleshooting a computer not connecting to the Internet despite having a Wi-Fi signal should be to check the network adapter settings. This involves verifying that the Wi-Fi adapter is enabled, the correct network is selected, and the TCP/IP settings are properly configured. If the network adapter settings are incorrect, the computer may fail to establish a connection to the Internet even though it detects a Wi-Fi signal. Updating the operating system, replacing the Wi-Fi card, or disabling the firewall are not the most appropriate initial steps, as they do not directly address the potential issue with the network adapter configuration.
