Just like computer programs have updates and service packs to fix bugs and add features, drivers do as well.If you’ve got a problem with a device, you should think about upgrading the drivers.For instance: video card drivers included in Windows rarely include all the features of the drivers you can download from NVidia or AMD/ATI, and they definitely don’t include the same speed enhancements.Whatever you do, don’t use some driver update software when you can manually pick the right drivers easily.Talk to any tech person, read any forum, and at some point you’re sure to be told to update your drivers… And is it necessary to compulsively update your drivers? In very simple terms, drivers are computer programs that let Windows and your other applications interact with a hardware device.
There’s a notable exception to this rule, of course.
If you let Windows automatically update, it’ll install right away and ask you to reboot.
If it fixes your problem, great—if not, you can always roll back the driver.
You might need to update drivers in Windows when a new piece of hardware you've installed doesn't work automatically or maybe after upgrading to a new version of Windows.
Updating drivers is also a great troubleshooting step when the device is having some kind of problem or is generating an error, like a Device Manager error code.
