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Correct: Updating the driver is a common troubleshooting step to resolve device issues, especially if the driver is outdated.

- 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.
