How To Update Drivers Manually

After your driver has been downloaded, follow these simple steps to install it.

• Find the device and model you want to update in the device list.

• Double-click on it to open the Properties dialog box.

• From the Properties dialog box, select the Driver tab.

• Click the Update Driver button, then follow the instructions.

Very important: You must reboot your system to ensure that any driver updates have taken effect.
