   • After installation, it may ask you to restart your computer to complete the process.

4. Install the Driver Manually via Device Manager (Alternative Method)

   • If you prefer to install the driver manually, you can do so through the Device Manager:
     1. Open Device Manager again.
     2. Right-click on the Intel Ethernet Controller X550 (or the unknown device under Network adapters).
     3. Select Update driver.
     4. Choose Browse my computer for driver software.
     5. Navigate to the location where you downloaded and extracted the driver files.
     6. Select the appropriate folder and let Windows install the driver.

5. Verify the Installation

   • After installation, restart your system (if required).
   • Check if the driver was installed correctly by going back to Device Manager and confirming there are no yellow exclamation marks next to the network adapter.
   • You can also test your network connection to ensure it is working properly.

Updating or Reinstalling the Driver

• If you encounter any issues with the driver (e.g., network performance problems), you can also uninstall the current driver via Device Manager and reinstall the latest version.

Troubleshooting

• If the driver installation fails or you encounter errors:
  • Ensure that the Ethernet controller is properly seated in its slot (for desktop/workstation PCs).
  • Sometimes, uninstalling the old driver completely (via Device Manager) and rebooting before installing the new one can help resolve conflicts.

This should cover most scenarios for installing or updating the Intel Ethernet Controller X550 driver on a Windows system. Let me know if you run into any issues!
