Once Driver Easy is installed, scan your PC using the software. It would find out all the drivers existing on the computer. It would also check whether all the drivers are updated or not.

Once the scan is complete, click the drivers that are flagged. Click the update icon, this would update the driver quite easily. Also, there would be an option 'update all'. This would be useful if you want to update all the drivers on the computer without any effort. Also, the software would notify you if a new update is available for the drivers on your computer.
