Day-to-day existence is free of thoughts about software drivers. But, as many computer users have learned, drivers can leave one scratching his head or pounding his keyboard in frustration.

Drivers tend to do their jobs well enough and that's why computer users rarely have to deal with them. The software scans the computer and then offers a list of updated drivers, which can then be installed from what the company claims is the largest database of drivers online.
