Driver updater's are fairly useless and often a scam. There's only one driver you need to update, that's your video drivers and you really don't need to update them unless you're having issues playing a new game.

If your computer is running stable and has no issues do not bother updating things regularly like the sound driver or the network driver, and other misc drivers. You are not gaining any performance by updating misc drivers all the time and are avoiding a potentially bad driver update.

Also if you have Windows 7 you can update them using Windows update, they will be suggested under the custom updates section.
