Updating windows device drivers
To download a driver directly from the manufacturer, navigate to the product page for the device in question.
Most websites will have a Support or Downloads page from which to grab the appropriate driver.
Download the installer, and install it like you would any other program.
If you have a laptop, you can often get drivers from the laptop manufacturer's website—they're more guaranteed to work with your hardware, though they may be out of date compared to drivers from the manufacturer of the component in question.
If you already have the manufacturer's driver software installed, you may be able to update your drivers from Windows.
If you're using Windows 10, it will say Check for Updates.
You can also go the long way by opening the Settings Update & Security. Once at the Windows Update screen, click the big Check for Updates button.
