Once the installation is complete, restart your computer to ensure the new driver is properly integrated and functional.
This simple process helps keep your system running smoothly and maintains compatibility with your hardware components.
Tech Tip: Driver downloads and updates come in a variety of file formats with different file extensions. For example, you may have downloaded an EXE, INF, ZIP, or SYS file. Each file type has a slighty different installation procedure to follow.
