You just purchased a mobile device. You want to synchronize your photos and music to your desktop computer running Windows 7. However, after plugging in the USB cable, you received an error stating that the device driver was not successfully installed. Which Windows system tools should you use to troubleshoot the error?

  1. Command Prompt
  2. Dxdiag
  3. Regedit
  4. Device Manager
  5. Services.msc

Answer: D – You should use Device Manager to troubleshoot the error. Using this tool, you can disable, install, update, or rollback device drivers.

Regedit is used to view/change system settings configured in the system registry. Services.msc is used to verify/start or modify the startup behavior of windows or app services. Dxdiag is used to view the detailed information about the DirectX components and drivers installed on your windows machine. You can use Command Prompt to run all these tools, but it is commonly used to perform tasks on your windows machine without using a graphical interface.
