Most applications that will automatically download and update your software come in a free scan mode. What this allows you to do is scan your computer to see if any outdated drivers exist before having to make a purchasing decision. In the case of DriverCure, RadarSync and VersionTracker, it will also scan your system for out-of-date software. Once your scan is complete, you will be presented with a list of hardware devices that either have an incorrect or outdated driver. In order to update your system with the latest drivers and software, you need to register and complete payment. We recommend having software that will do this for you because not only does it save you dozens of hours of computer maintenance work a year, it will keep your system updated through-out the year. This ensures that your hardware and software behave as they should: problem-free.
