1. First, through the Start menu, right-click and select Computer and Administration.

2. Enter the "Computer Management" page, and you can see the devices with exclamation marks (indicating that drivers need to be updated). Right-click and select Update Driver Software.

3. Select the driver (by automatic search; You can also select the appropriate driver folder). Generally speaking, after downloading the driver, please select the folder of the driver.

4. Select the appropriate driver folder, and then click OK to start updating the driver.

"Windows Security" prompt will appear, and select "Always install this driver software". Please wait a moment to install the driver.

5. Right-click my computer again and select "Manage". After entering the Computer Management page, the exclamation mark you saw before will disappear (as shown below). At this point, the driver has been successfully installed.
