A customer called the help desk to report that a new USB CD drive is not working. Which of the following tools should the technician use to diagnose the issue?

lusrmgr.msc opens Local Users and Groups Manager, which is used for managing user accounts and groups on a local computer, and has no relevance to troubleshooting hardware devices.

devmgmt.msc opens Device Manager, which is the central utility in Windows for viewing and managing hardware devices and their drivers. It allows a technician to check if the USB CD drive is recognized, if its drivers are installed correctly, if there are any conflicts, or if the device has error codes, making it the ideal tool for diagnosing hardware issues.

certmgr.msc opens the Certificate Manager, used for managing digital certificates, and is unrelated to diagnosing hardware functionality.

perfmon.msc opens Performance Monitor, which is used to analyze system performance and resource usage, but it does not directly help diagnose why a specific hardware device like a USB CD drive is not working.
