To perform a full-system driver scan and update any older drivers in one easy step, you will likely need to download or install a driver updating program. For performing a driver scan on individual devices, you will need to access the device manager in Windows®. Different versions of Windows®, for example, typically allow you to update your hardware and device drivers in different ways. The precise way in which you can perform a driver scan depends a great deal upon what type of computer you are using, specifically the operating system (OS) type and version that is installed on your computer.
For the latter, you will likely need to choose a software program designed to scan your system for old or outdated drivers and find updated versions for them. You can search for and update individual drivers for specific products or hardware, depending on what you are having issues with, or you can perform a full-system driver scan that will allow you to update the drivers on multiple pieces of hardware at once. There are a number of different ways to perform a driver scan, and how you go about it typically depends a great deal on what exactly you are trying to achieve and update.
