Should You Update Your Drivers?
I've seen ads for software that scans your computer, looking for device drivers that need to be updated. I'm not even sure what a driver is, but if everything seems to be working fine, do I really need to update them?
What is a Device Driver?
Device drivers, commonly called just "drivers," are small programs that act as translators between your operating system and the hardware devices it uses. Every hardware device needs a driver. Your printer, scanner, mouse, keyboard, hard drive, graphics card and network adapter are all examples of devices that require a software driver in order to respond to commands from the operating system.
For example, when you hit the Print button, Windows issues the generic command "print," and a device driver translates that command into the specific instructions needed by your particular make and model of printer.
Windows comes with a vast library of drivers. When Windows is installed, it scans your computer for attached devices and tries to match them with drivers from its library. Likewise, when you plug a new device into a Windows system, Windows looks for an appropriate driver in its library. If the right driver for a device is not in Windows' library, you will be prompted to supply it (typically, on a CD included with your hardware device).
Install the driver and you're done, right? Well, not always. Hardware makers do issue updated drivers occasionally. Whether you install them or not is up to you.
Do I Really Need This Driver?
Most driver updates are performance-enhancers. They may fix minor but irritating glitches in previous versions. Often, these glitches are so minor that they pertain only to particular PC models and do not affect the majority of users.
Sometimes you'll need to update a device driver if you move to a newer operating system. For example, you might have a printer or scanner that worked fine under Windows XP. You upgrade to Windows 7, and now it doesn't work. A quick trip to the vendor's website should help you find a driver written specifically for that device and operating system. In most cases, you will simply download and run an EXE file to install the new driver, then restart your computer. If that's not the case, look for instructions on the vendor's site.
A few driver updates patch security vulnerabilities that might enable bad guys to infiltrate your computer - if they bothered to take advantage of the vulnerabilities. It's just not worth a hacker's time to write a virus targeting the driver for one of several thousand devices. Beside, security-related driver updates generally find their way automatically onto most users' systems via Windows Update.
Most people don't bother looking for driver updates unless they are having a problem with a hardware device. After all, it isn't broken, why fix it? By the way, Windows Device Manager is not a reliable indicator of whether your drivers are up to date. Device Manager tells you only whether a driver is working, not whether it's the latest and greatest version.
Watch Out For These Driver Update Gotchas
There are many so-called "driver updaters" available online. These programs scan your system's drivers, tell you which ones are out of date, and offer to fetch and install the latest drivers for you. Sounds neat, until you realize there's a fee for all of this. Then you may also realize that you have no way of knowing whether the drivers installed by such services are really the latest drivers, or even if they are malware in disguise.
Don't just Google the name of your device and download a new driver from the first website that pops up. Aside from Windows Update, the only trustworthy source of drivers is the support website of the hardware manufacturer. If you are having an issue with a particular device, look for a more recent driver on the maker's site. But updating drivers just for the sake of "keeping current" is not worth the effort.
