Once you download your new driver, then you need to install it. To install a driver in Windows, you will need to use a built-in utility called Device Manager. It allows you to see all of the devices recognized by your system, and the drivers associated with them.
Install Drivers Manually With Device Manager
Open the Start menu and type "Device Manager" in the search bar. Click on Device Manager when it appears in the search results.
In the Device Manager window, locate the device for which you want to install or update the driver. You can find devices under their respective categories, such as Display adapters, Sound, Video and Game Controllers, or Network adapters.
Right-click on the device and select Update driver from the context menu.
In the next window, choose: Browse my computer for driver software
Click on the Browse button and navigate to the location where you saved the downloaded driver files. Select the appropriate driver file and click OK. Then, click Next to begin the installation process.
After the installation is complete, you may be prompted to restart your computer for the changes to take effect. Save any open work and click Yes to restart your device.
