The DriverCure review have given good insight on the program. But I was still a little confused on what it did till I checked it out myself. First off is scans your computer to see what drivers you need. Then it helps you download the new drivers. It also keeps a log to keep you up to date. It also has a way to let you return to old drivers if needed. Finally it is backed by customer care and support if needed. The system does so much more than just updating old drivers. It is a life saver and great program.
