1. Create a restore point(Start → "Create a restore point" → Create), so you can roll back if anything goes wrong.
2. Verify compatibility: your Windows version (Windows 10, Windows 8.1, Windows 8) and architecture (x64)must match this driver, and your device's Hardware ID should appear in the list above.
3. Download the file using the button - it comes directly from Dell official catalog.
4. Run the downloaded installer and follow its steps. Reboot if the installer asks for it.
5. Check Device Manager: the device should show no warning icons, and the driver version should match.
