DriverIdentifier is a desktop/web app hybrid — install the program then launch it to scan your system for all device drivers then the program checks to see if there are new drivers available for your hardware on the web and these results are displayed in a browser tab. Any needed driver updates can be directly installed by clicking on the Update link.
The program is relatively straightforward. Running it on my Lenovo laptop resulted in a handful of drivers that need updates such as my webcam, graphics card, and SATA controller. Clicking on the update link takes you to a page with several mirror sites from which you can download the driver, but watch out for the big green “Download” button which is actually an ad; the real download buttons/links are less obvious.
This program will be great for yearly updates of your mum and dad’s computers. Most people who read Lifehacker keep their own systems regularly updated, but if you’ve fallen off the wagon this free program is a good utility to get back on track.
