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) 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.

If the device stops working after the update: Device Manager → right-click the device → Properties → Driver tab → Roll Back Driver. If the button is greyed out, use the restore point from step 1 (Start → "Recovery" → Open System Restore).
