Explanation

Device Manager is a critical tool in troubleshooting hardware and driver-related issues. To resolve a non-functioning device like a webcam, you can try updating the driver, reinstalling it by uninstalling and rebooting, scanning for hardware changes, or rolling back to a previous driver if a new update caused the problem. Disabling the device, however, does not address the issue and is not a relevant troubleshooting step in this scenario.

  • A. Correct.

    Correct: Updating the driver is a common troubleshooting step to resolve device issues, especially if the driver is outdated.

  • B. Incorrect.

    Incorrect: Disabling the device will render it non-functional and does not resolve the problem. This is not a solution for a malfunctioning driver.

  • C. Correct.

    Correct: Uninstalling the device and restarting the computer forces Windows to reinstall the driver, which can resolve corrupted driver issues.

  • D. Correct.

    Correct: Scanning for hardware changes can help detect and reinstall missing drivers, which might fix the issue.

  • E. Correct.

    Correct: Rolling back a driver can resolve issues caused by a recent driver update if it introduced compatibility problems.
